Never noticed this thread until now but if I had I could say the beta software for XP is out for about a year now.
I don't have a 3Sixty-2 yet because they are way too expencive over here in Europe (699€ --> 1025$) so I'm planning on ordering one in the States (399$ --> 272€+shipping

).
But I have been trying out the demo of the software in the past. It looks really nice and easy to use but there is one disadvantage for us CarPC minded people and that's the fact that it will only run on a resolution of minimum 1024x768. Since most of us are running 800x600 or 800x480 we will have to change our resolution everytime we want to change something on the 3Sixty.
But anyway this still beats buying a Palm only for using it with the 3Sixty.
