Really ? Then if that is logically true and correct, there is no need for those duties beyond a simple 486. It does all of the described duties, does it not ? Yet why is it that we have to spend top dollars for something you people describe as just being able to "e-mail", "internet", "type an essay" ?
By the way, my friend uses a toshiba laptop, 486 with 8mb of ram, and does everything from coding C to typing up research materials and have no desire to upgrade, ever. Obviously people look a little further into their computers when they empty their wallet or bank account. People never buy a computer to JUST use the keyboard to type up letters or stare vaquely at the screen for information, do you have legs JUST to walk ? No! You run, jump, prance, mince and scuttle perhaps, there is but a thousand different uses for legs we have daily, nature would've never gave us legs just so we can walk, or we would have never made it through evolution. And what about your brain ? Did you receive all that education JUST to be able to tell me "people get an iMac just to type, browse, listen and watch ?" I sincerely hope NOT. An iMac is nowhere as specific as a blender is a kitchen tool, both are tools, but even my blender can blend protein shakes, beat up eggs, crush ice, and make other refreshing drinks, there is no way i'd buy it if I expected a blender just to blend 3 or 4 of the most popular drinks.
Think clearer, not louder.
