(title)...because we can!
no seriously though, why do people spend more money on other brands? why do people spend more money on ANYTHING?!!? cuz they want it faster, smoother, sleeker, smaller, more atttractive, and more flashy. it's human nature my friend. When the latest comes out, people are enticed to get it becase what they have is labeled "old, outdated, slow, bulky, obsolete" by the advertisers. It's an easy trick and an easy game to win if you are on the selling side.
My computer is "low-midrange" now-a-days' i think, but it still run pretty well for my uses. When i get an A64 setup...i will have NO IDEA what top use it for or what to do with all that power. After a few months...i will definetly find some good games to play and all of that...but could i SURVIVE on the setup i have NOW for a few more years...sure i could.
