I've been using the Daz unlocked ultimate for a while. Basically the only feature I have used is the vitual windXP for one program, there is another program that I use even more frequently that won't work with the virtual XP so I have to boot my XP drive. I guess what I am saying is it doesn't seem that the Ultimate version is worthwhile over Hom ed for me. Well the bitlocker is nice, but I am sure I could find a third party solution. Does anyone know the disc space saving by going with home ed vs ultimate?
