I'll say this...I've never been a Mac person but I do find the new Macbook Air very attractive. In the past few years I've had a Dell Inspiron (my current laptop), an HP Pavillion, a Lenovo, and an Acer. They've all been bulky and prone to overheating, and the battery life is terrible. My current Dell started at about 3 hours but now I'm down to about 30 minutes.

As a developer, the only software I need is Zend Studio and Adobe CS, which are both available on Mac. With the increased portability and longer battery life, the Macbook air may be just the thing I need. I'm looking at the 13 inch right now, and I'm strongly considering buying it.
