I'm running Windows 7 Starter on my netbook. I've never had a full or infinite freeze or had to shut it down without returning resources. That I know of, Starter has no less system requirements than other Windows 7 packs. Windows 7 is more than just Microsoft scrambling to fix Vista, It feels like an entirely different OS! I have to use DOSbox to run stuff like DOOM, and I all in all can't run Sonic R, but that's as much compatibility problems I have.
