Let's say I'm a computer gamer. I'd want to spend most of my money on a high-end video card to handle the graphics and maybe a really terrific monitor, but skimp on things like a printer and a scanner. Identify the components you won't likely have to replace every year or so and spend money on top-end components that are unlikely to go out of date. For instance, some of you might want to look into a really cool flat monitor, or a regular monitor that's 19 to 21 inches. If you get a good monitor now, it'll probably last you through three or four computers.
Printers also are a relatively stable component.
Inkjet printers have gotten a lot better over the past three or four years, and the top-end models today are liable to last for a long time. If you follow my strategy, you'll soon be in the position of just replacing your computer processor, as needed. If you get a midrange computer as far as speed, it may well last you for two or three years if your prime use is e-mail, letters and simple tasks like figuring your taxes. Try my system. I have a selfish motive, of course.
