I was using Xandros 3.4 for over a year. I purchased my disk from Fry’s electronics for like $29.
Well I saw in all of the help forums for modding of Xandros desktops and boot screens tons of help but it was all for 4.0 so I installed 4.0 . It really looks good and comes with a blue launch button as opposed to the default red I had to use with v3.4 . Quite nice. I changed the start button to a modified that I found through the links of the Xandros forum. with 3.4 when you changed the launch button you kept getting a notice to upgrade service pack, even if you already have. When you do the service pack upgrade it changes your launch button back to default. but with 4.0 , no you do not get forced into the change. Nice addon I like this.
When I installed wine again, not a hiccup one. Not one issue. It went great. My Grand Theft Auto Vice City and San Andreas both play nicely and my III does not freeze up on the video configuration like it did with 3.4.
I am happy with 4.0 it was a very good move.
I was there at Fry’s to actually by a new motherboard and nvidia video card so I could prepare myself for Vista. Thank god I did not get into that mess. Xandros is really good. I did of course remove my Ubuntu partition. Ubuntu is not pleasant at all. Even though Ubuntu is Debian just like Xandros; it does not come close in comparison to Xandros with features. I am satisfied and I hope this helped you decide what you will do to you computer.
enjoy.
