I installed Debian Lenny RC 1 on my 2GHz Pentium 4 that I just bought from dad. It boots from GRUB in about 18 seconds! That’s just out of the box, and I think I’m happy with that. One of the nice things I noticed is that it disables the netinstall CD in sources.list before rebooting. One of the surprising things is that it beeps for a bit before bringing up the main menu. Not sure why. It’ll probably be a BOINC Zombie and occasional game server.
