Definitely use EC2. There is no point in owning hardware anymore unless you have a poor Internet connection or you're running a local application like a media server. Of course, this is above and beyond a reasonable desktop/laptop which you'll need for local development, management etc...
I personally use and love Macs (switched about a year ago). I wouldn't go back to Windows for $1k (and I used to be a Windows Server Admin - actually, their server stuff is good).
When you're on Mac, you'll need a good package manager. I recommend MacPorts and Porticus.
As for which Mac, get the iMac or MacBook with an external monitor, mouse, and keyboard.
Buy TextMate also for editing.
