Hi: Just wondering if anyone knows how the Air (either Rev A or B) stands up to programming, specifically using IDE's like JDeveloper or Eclipse. Im undecided between the Macbook (which I would upgrade to 4GB) and the Air (purely because I really like the form factor). I know the Macbook would be the better performer but wondered if the Air could cut it for such tasks. JDeveloper states system requirements of 2GB. I have used JDeveloper on a windows box with 2GB - I would hope this would mean it would be OK on the Air? Just looking for some real world experience as its not something I can try in the Apple Store (I think)? If only there was a BTO option of 4GB with the Air!
