Been using it for about three months and on ballance I think it's significantly better than 10.
It loads the databse faster, so takes less time to boot, and it burns CDs that lways play in the car (as long as I use cheap Tesco supermarket brand media rather than more expensive Maxell brand) - WMP 10 made about 30% coasters.
Overall, I'm happy.
And it's better in black.
