Here's the problem, though: Siegler and I can't talk about intense applications. I don't know if it can't handle RAW file editing in Lightroom/PS, Starcraft II on high settings, or developing in Xcode. The benchmarks Siegler quotes show the Air is worse than the 13" Pro at handling these intense apps (Handbrake, PS, VM software). [1]
Someone cracked about how Siegler's activities consist of "blogging and scrolling through Twitter." For anyone who does that (i.e. your average college student), this thing will be great for years.
For more intense apps? I have my doubts. And the Air might be fine right now, but what about upgrading two years from now? What if system or available memory become an issue?
