Wolvix used to be my favourite distro for smaller lighter machines. Now i prefer SliTaz. I've even found a LiveCd work on a machine with a fairly broken Cd-drive! ie a Cd-drive that other OSes can't even see.
Dual-booting with Windows is an excellent way to run a computer, especially if you like gaming. However, Wesnoth and Glest are magic so i am ok. Companies need a lot of us to tell them that producing 1 OpenSource version would quickly cover all Linux's as well as Mac. OpenGL beats DirectX for cross-platform gaming mio.
