Are you sure you do that all at once without slowing down on a MBA with 2GB RAM? I just tried my regular use case - Mail, Firefox, MS Word and Excel plus Adium and it was 350Mb into swap and switching apps wasn't all that instantaneous.

What does your swap usage show (Activity Monitor - page outs with all that workload?

However with 4GB it shouldn't be that much of an issue for this workload. So I might just bite the bullet given the Sandy Bridge and TB upgrades!

I have for the last 12 days, and this was after using an iMac from years back which processed everything excessively. Right now my swap usage is 640 MB. Worth mentioning, I am returning it tomorrow to get the latest offering. Probably in the same setup.

Especially $100 bucks more for an i7 chip.
