Your Dev Environment
swoodtke: I use VM's on a MacBook Pro circa 2006 and they worked fine - a little slow on harddrive intensive operations (e.g. startup, building large applications) but useable.Then I got an SSD harddrive.  It's like I'm using a new (much faster) machine.  The VM's seem like they're native.SSD HD's are still pretty expensive but worth every penny IMO (and way cheaper than a new MBP).
