Does anyone remember how just 10 years ago or so, we could run quite happily on a computer with 4MB of RAM? And it did pretty much everything our modern computers do, and often just as fast? Our desktop machines right now are way, way faster than even the fastest web server from a few years ago. Hardware gets better and better, and software gets suckier and suckier.

According to one of my professors (and this was two years ago, so this statement is even outdated), the computer each of us has on our desks has more computing power than every single computer in the entire world in 1970 (or so) combined.
