I have had my MBA for about two weeks now, and it has been pretty good to me so far. I got a stock model, no external HD but with an ethernet dongle (which sits in my kit bag with my modem dongle). I was sick and tired of carrying around a MBP (size, weight), and once I had a chance to feel the computer in the store, I was sold.

First thing, the form factor is great. Fits inside my existing bags no problem, well, mostly fits in the small side pocket of my main travel bag, instead of the main computer pouch The computer *feels* solid. Not flimsy at all. I don't worry about damaging it by breathing on it.

The power adapter is small, 45W, which means I will finally be able to power and use my empower adapter properly (the MBP was 80W, which overwhelmed some airline systems). Same problem using AC's normal power port, as it is recessed and the Apple designed bricklet doesn't fit properly. I have a small 5$ extender I use in this situation. This is something you need for any Apple computer, and is not an MBA issue. When traveling on AA or UA, my Empower magsafe adapter works fine.

Haven't missed the optical media drive yet, and only missed the lack of 2 USBs once. I use a 3G network adaptor via USB, and I wanted to read a memory stick. Deal breaker? Not so far.

Power? I get on average 3.5-4 hours of use. Standard settings. Bluetooth is off, WiFi is on if no 3G card in use. I find power is sucked down by my 3G internet connection (it was in my MBP as well). It charges slowly.

Much cooler on my lap than my MBP.

The keyboard is nice, but I find the effort to press the keys is harder than I am used to - reminds me in that respect to the old school IBM keyboards of decades past. But there is surprisingly good movement on the keys.

First time ever I have moved to a slower computer from a faster - it mostly is the HDD I think. It is noticeable from a MBP, but I was playing around with a MB, and it felt the same. Given that the MBP is one of the fastest notebooks out there this is of no surprise!

I run on this computer a customized install of Adobe Master Collection, Lightroom, MS Office 2008, my iTunes library, and some small work based apps. I have about 30Gb left on the HDD.

My office computer is a new iMac 24", which runs a full meal deal of the apps above plus VMWare (usually running 2 VMs). I do not have a reason to run VMWare on my MBA.

This is the right computer for me. For you? Not for me to tell you. But this is my primary computer at home, and outside of the office. I do more than just Word on it. I edit photos, make podcasts, design websites, maintain web applications, and make presentations all on my MBA.

I have found myself replacing my PDA in meetings with it. It is easy to carry around the office, and is so much easier to plan or work with than any PDA I have ever used.

So so far, so good!
