I’m pumped about the rumors of an upcoming $500 headless Mac (i.e. no integreted monitor). I thought about switching to the Mac when I made my last computer purchase, but I didn’t want to have to switch to all new software. A little thin Mac that could share my monitor, keyboard, and mouse with a KVM switch would be a great way for me to replace my current Linux box that manages my TiVo info. And OS X is much prettier and user-friendly than my command-line Debian setup.
