i have to echo the sentiments on macbook air. i made the decision to convert to apple about a month ago. i was all set to buy the macbook air (i will admit that form factor plays somewhat of a role in my purchase decision). i also travel a lot and i ALWAYS handcarry my laptop for security purposes.
so after a few visits to the apple store and a lot of research on the internet, i decided to get the base macbook instead. i love the mac OS, and the specs-for-price ratio is far superior to the air.
form factor? the grand arbiter of all things fashionable (my wife ;) ) actually thinks the base white macbook looks cooler than the silver air
