Hi, could have chosen a Pro over the Air, but went with the Air (Rev A). Agonized for 2 weeks over decision, went to Apple store twice, bought the Air. Never once regretted it for a single moment, not once. Machine works perfectly. I was concerned about the 2 gb ram limit, but it has not been an issue. Held off on the external DVD, glad I did... didn't need it, or miss it either. Apple has a long track record of ditching things we think we still need, we whine, but often they were ahead of the curve. When I bought the first Biondi Blue iMac for my family, the first comment was "ccol", the second was "I would never buy a computer with out a floppy drive, what would be the point?".
Anyhow, at the around $999-1150 they are going for now, they are a steal.
This machine insights trolls and naysayers like none I have ever seen before. If it isn't for you, you don't have to buy one, but why tell everyone about a computer you don't have, or don't use (or "bought" one, but "sent" it back... my favorite fable, lol).
I use Aperture, CS suite, Quark, Rapidweaver, hook it up to my projector for meetings, watch movies, etc. It is not a primary workstation, but I can indeed work on it. Watch the little vents on the bottom, especially if it is laying on a squishy cushion, which will block the vents.
Good luck.
