I've just ditched Windows XP on my main PC in favour of Ubuntu 8.04 Hardy. I reinstalled my Windows license on a virtual machine using VMWare (
) so I can run those few Windows programs that I must have.
My machine now boots in 40 seconds as opposed to 3.5 minutes and everything runs in half the time. And I don't miss having to use Ctl-Alt-Del...
I also use Ubuntu on all my old PC's (the 486 ones with 512M RAM) so the kids have their own machines for homework. Works most excellently!
Ubuntu is quite mature now and I think it's more a viable alternative for the average bloke (and gal) on the street.
