If cars were like computers,this year's model would be morepowerful than last year's, havemore features, and be cheaper.For $400, you can get an off-the-shelfPC that can run ringsaround that clunker you paid$1000 for 5 years ago. In fact, for$1000 today, you get a chipthat's more than 10 times fasterthan the one in your 5-year-oldPC (512 megabytes of RAM comparedto 16) and a hard drivewith 60 times the capacity.

Price wars haveled to cutbacks in other areas,like customer service. Be preparedto spend more time onhold if you need technical help.
