Desktops are in the same boat. I've been looking around to replace my SEVEN year old desktop. CPU performance, going by PassMark score, looks to be about twice as fast now as mine. Twice the speed is a nice upgrade, but only doubling the speed over seven years? I think about a seven year span like 1994-2001 and going from a 486 DX to a Pentium 4 would have been a whole different story.
