Buying a Computer
"I teach senior citizens in a community based computer lab. They often ask what to look for when buying a computer, what software they need for email, basic Internet usage, word processing, etc. Many are on a limited budget. What would you suggest they need as a minimum?"

Buying a New Computer
The good news is that computer prices have dropped a lot over the past few years, and the computing power you get for your money is going up! I don't recommend used computers for anyone, because the rate of change of computer technology will make most systems nearly obsolete within three years. And used computers often come "pre-loaded" with viruses, spyware and damaged system files. If you're a computer novice, wondering what kind of computer, monitor, hard drive, memory, and operating system to get... here's some advice to get you rolling.
Windows or Mac?
You may have friends, relatives or neighbors trying to pull you into the "Windows vs. Mac" holy wars. In my opinion, the choice of operating system really doesn't matter. From a beginner's perspective, each has point & click interfaces that are pretty easy to use. Both will take you to the same Internet, and enable you to send and receive email. Both offer word processing, and the documents they create are interchangeable. Because Windows-based computers make up 90% of the market, they are cheaper. It's the law of supply and demand in operation. And in some areas, it may be hard to find technical or repair support for Apple Macintosh computers. So if you're budget-minded, and you don't have any friends willing to help you with Mac issues, I suggest you go with a Windows-based PC. But if all your friends have Macs, and you don't mind spending a bit more, then buy a Mac. Like I said, they both take you to the same Internet, and the user interfaces are very similar.
A good entry-level Windows-based computer with monitor can be purchased for under $400, and sometimes you even get a printer in the deal. A Mac Mini goes for about $600, but that price doesn't include a monitor, mouse or keyboard, so figure around $750 total. So what should a newbie look for in terms of speed, monitor, memory and hard drive specs? It doesn't have to be all that confusing...
What about Horsepower?
The CPU (central processing unit, or "processor" for short) is the brain of your computer. In general, the faster the better. Processor speeds are measured in gigahertz (GHz) and as of this writing, the fastest models available operate at about 4 GHz. Entry-level machines start at 1.5 to 2.0 GHz and are more than adequate for web surfing, email and word processing. If you see a computer with a processor that has a speed specified in megahertz (MHz), steer clear -- these are older models. (Tech Note: 1 GHz is equal to 1000 MHz, so an older 300 MHz system will be about seven times less powerful than today's entry level machine.)
Thanks for the Memory
The next decision you have to make is how much RAM memory you need. Don't confuse RAM with hard drive (file storage) space. RAM is the temporary working memory that your computer uses to perform calculations and manipulate files. When you open a document, it is copied from the hard drive into RAM. As you and your word processor work on the file, the modified copy exists only in RAM. When you save the file, it is copied from RAM back to the hard drive, or permanent storage. And as with CPU power, the more RAM you have, the better your computer will perform. I recommend you have a minimum 256 megabytes (MB) of RAM, but with 512MB or 1024MB (one gigabyte) you'll notice better performance.
Hard (Drive) Decisions
The hard drive is your permanent file storage. All of your personal files, such as word processor documents, photos, music, and emails are stored here, in addition to software packages and the operating system. Most new PC's come with a hard drive that's 80 gigabytes (GB) or larger. I recommend you start with a hard drive of 80 GB, or more if you plan to keep lots of photos or music on your computer.
Go For a Large Monitor
Here's the formula: Larger Monitor = Less Eyestrain and Less Scrolling. I recommend a 17-inch monitor, or even a 19-inch if you don't mind spending a bit more. Don't worry about brand names here, they're all pretty much the same. Stay away from 14 or 15-inch monitors, they're just too small to be practical.
What About Software?
Most of the software you need will come pre-installed on your new PC. Windows comes with Internet Explorer (for web browsing) and Outlook Express (for email). Many PC systems include a word processor, such as Microsoft Word, WordPerfect, or OpenOffice. Likewise, Mac systems come with the Safari web browser and Apple Mail for email. If your computer doesn't come with a word processor, I suggest you purchase Microsoft Works for Windows, or iWork for Mac, both of which will give you a capable word processor and other useful programs.
Anti-virus and Spyware Protection
Windows users, look for a computer that comes with anti-virus software pre-installed. If yours doesn't come with any anti-virus package, check with your Internet service provider to see if they offer anything for free. My article Should I Buy Anti-Spyware or Anti-Virus Software? will tell you my recommendations for FREE anti-virus, anti-spam and other security tools.
Summary
So in a nutshell, here are my recommendations:
Where to Buy?
Look at your local computer store first, they may have some good deals and offer local support. Office supply and electronics stores such as Staples, Office Depot, and Best Buy are good options to explore too. If you're comfortable buying online, check out Dell, Gateway, Apple and be sure to read Kevin Savetz' Guide to Buying a Ridiculously Cheap PC.

Great answer and suggestions! Newbies are so fortunate, today. They get "more bang, for their buck" than those of us, who purchased our first computer back in the 90's. In September 1997, I spent over $2100 for a Cyrix 166MHz CPU, 16MB SIMMS, 1.3GB hard drive, ViewSonic 15" monitor and an Epson Printer. The computer system was $1200, the monitor was $500 and the printer was $400. I had a friend with computer knowledge helping me and I bought through a catalog, so there were shipping and handling charges. My friend also, taught me how to repair and upgrade, he was my mentor, then I learned more and would repair or tweak his computer. Plus, I learned how to repair, tweak, build and fix, after the age of 54. Not bad, for an old broad, is it? Just look at the prices, you are suggesting. Today's computers are at least a thousand times more powerful, even the cheap ones! The prices you suggested are great for senior citizens. Many are on "fixed or limited" incomes, like I am today, and must save to purchase their first computer. Once again, great article and suggestions. |

Bob, good article for newbies. Wish you would have mentioned that DIY PC's are almost always much better than store bought. The components have longer warranties, more expansion space, are upgradeable, and full feature software that's fits the builder. Finally, all those expert friends shut up when you tell them you built your PC from scratch! The downside is they call you with all there problems after the 1 year store bought PC warranty expires. |

Bob, in the beginning of the comments you touched on the subject of different processors. Please note that AMD uses a little different technology that doesn't require extremely high processor frequency to preform at the same level as their counterpart, Intel. I have been highly satisfied with AMD processors and will continue to use them in all of my builds unless requested by a customer to do otherwise. |

Bob, I wish you had mentioned the issues of heat and noise. Today's powerful computers produce more heat and that has to be exhausted somehow. I have a computer that came with a fan so loud that it sounded like a hair dryer was running inside. After complaining, the maker substituted a somewhat quieter fan. I have since upgraded the heat sink and fan and it is worlds quieter. Generally quieter computers are not an accident. They are built by design and sometimes it is worth weighing the cost benefits of less noise. Thanks for the great information. |

A well balanced piece of advice aimed at a specific user. What i would say is that based on my "older" father's experience, he very quickly discovered the wonders of computers that lies beyond the daily menial task of writing me emails and trying to find his way around the internet. The thing is if you use the internet you see that there is a massive and exciting world of multimedia, and I humbly suggest, based on one click comparisons, that if you go for a Mac as opposed to a PC, you get the complete set of iLife software included which cuts out a huge learning and research curve for organising and playing with photos, movies, music blah blah blah. I would also say that looking at my brother's Windows/PC experience, he has bought two cheaper PCs for every Mac I have owned. He is a bit of a geek, so sure he gets good use out of them, he has them dancing almost, and he does get good deals, but he has spent more on his computers than I have. |

Can you tell the differents between a Dell solo processor and a Duo processor, Not sure what would be the best for me. EDITOR'S NOTE: How fast can you type? If you're not using game or graphics editing software that demands lots of horsepower, then don't pay extra for a hot PC. |

I would like to second the request for a good laptop review, or laptop PC comparison (maybe a link to someone who has done this already?!!). I use only laptops at work and have for the last 4 years. They are great. At home I use a PC and find it has obsolesced quickly, so am considering a replacement and possibly a laptop instead of a PC. Your suggestions and evaluation of this idea will be most appreciated. Thanks. EDITOR'S NOTE: Using a laptop instead of a desktop is great for people who are very mobile. But laptops tend to have a much higher price/performance ratio. You can buy a lot more horsepower for your dollar with a desktop. And I've never found a laptop keyboard that I found comfortable for typing. I like my Sony VAIO but only use it when travelling. |

(If you want an easy way to get the great prices and services on computers, go to www.dell.com/dellchat). Only works if your inside the US though. EDITOR'S NOTE: Why... do they offer lower prices if you start a chat session? |
