I'm contemplating one of two things: Selling my 2.6 MBP and buying a 1.86/128 MBA or Keeping my MBP and ponying up for a first gen Air I only want the air because my MBP is so cumbersome in both size and weight. I love it, and I'm a tiny but afraid of losing so much power... but the RevB Airs are supposedly greatly improved. I have a mac desktop for my somewhat heavy lifting (conversion, etc). I don't like the idea of having two laptops though, keeping them synced is a pain in the butt. Financially they're about on-par with each other so.... opinions?
