Spend some time reading up on the person who said that 640K is more than anyone would every need. Same concept
Came to say this very thing

Seriously though, think about it logically for a bit:
1. Improved CPUs will enable better/more complex apps down the line
2. Everything loads instantly? Really?? A lot of non-gaming apps lag still
3. If you don't game, doesn't mean others don't. It's a HUGE market as 14-25 year olds are the prime audience for both smartphones and games.
4. New multi-core CPUs make multitasking very noticeably better. I remember switching from a single-core athlon to a core 2 duo and being blow away by how much adding a core improved the performance vs just increasing the clock speed...
