Well after bouncing back between Mandriva 2008.1 Spring and Kubuntu 8.04 for most of a week I went ahead and pulled the trigger, installing Kubuntu as a dual boot beside Win XP. I really want to try Mandriva out and will find a machine for it eventually but for now Kubuntu won out. My newest PC in the house runs Mythbuntu (MythTV + Xubuntu) and I am really wanting to try to get this laptop to act as a front end/player for the Mythbuntu back end/server and I figured it would be easiest if I kept it in the 'buntu family so to speak.
The truth of the matter is though, after a few days of Kubuntu being available, I don't find myself using it all that much. So far Win XP is a champ on this machine. Firefox3 is humming along just fine, OpenOffice is taking care of all of those needs. This evening I did some free-wifi surfing at Panera Bread inside of Hotspot Shield's VPN, something I could not have done with Kubuntu or any other Linux distro that I know of.
So for now, Monty's D410, although technically dual-boot, is mainly a Win XP machine. If I get the MythTV under Kubuntu things may change and the Linux side of the machine may start pulling equal time.
