At work we all use the higher spec 13" air's - keeping our dev environment inside linux vm's that run locally.. I run a few windows vm's for front end testing but we do have a beautiful windows machine sat in the corner too - as long as I don't try and run everything at once its fine, with the benefit of having the lightweight machine to take around the place..

Do you always stay connected to the internet when you need to work / how much would it affect your productivity if you weren't able to access a remote server? I imagine the latency would get annoying, even if it were minor.
