I'm also in the process of making such a decision. I was originally attracted to the Mac by the new 17" MBP, specifically by the low size / weight ratio and the long battery life. When I went in to the store to look at it, I saw and loved the MBA.
In terms of my profile, I'm a consulting exec who travels extensively (4-8 flights per week), and I'm looking to replace my work laptop and home machine with a single laptop, where I can run a virtual image of my Windows work PC to get access to Outlook, Visio & Project, client VPN software, etc., house my personal files and apps, and maybe play the occasional game (not into 1st person shooter games, so the integrated graphics on the MBA aren't the biggest deal)
I know I'm looking at the two extremes of Apple's offerings, but as I look at it, those two machines offer something not currently available from other manufacturers, namely the Air's unique form factor, and the MBP's power, screen, battery life, etc. in a < 7lb package.
I'm not that concerned with the storage on the Air. My current ThinkPad laptop only has a 60GB drive, and I'm still 15GB short of filling it, and that's without ever really having paid much attention to optimizing the disk space. Also, I'm using my Airport Extreme to host a 1TB drive for file storage, and plan to make that available over the Internet, so things like photos, old work files, etc. can just live there.
I'm also not that concerned about the limited ports, etc. on the Air. I rarely use my optical drive anyway, and I'm fine with carrying a small hub to run my USB peripherals.
My three real concerns on the Air are
1) Whether the 2GB RAM would prove to be too little to run VMWare Fusion for my Windows needs and the other apps I need. In my typical day, I usually have Outlook running all the time, plus several Word docs, Excel Files, and/ or PPT docs, open at the same time, plus a browser window or three.
2) Whether the MBA battery would be sufficient for my needs. My heaviest battery use comes when traveling, and I do fly coast to coast relatively often. With Wifi off on a plane, and the screen dimmed, what kind of battery life should I expect?
3) Whether the non-upgradability of the RAM would limit the useful life of the machine too much. As this is a personal purchase, I'd like it to last a while.
Any thoughts appreciated.
