Macbook Air 13" has basically everything you need. Upgrade to 256GB SSD and 8GB ram and just do without the possibility of upgrading to 16GB ram. The Haswell more than makes up for it. Been using one for a month and loving it.

I have the 2013 MBA and it's great. Surprisingly the 8GB of RAM hasn't bothered me. It may be the fast swap because of the incredibly fast SSD (800mb/s r/w) though. I have no problems running multiple Linux VMs with Xcode open.
