Got mine yesterday from modmypi. Very nice bit of kit - so snappy in comparison to my old RPi.
OpenElec is butter smooth but the big difference was navigating around rasbian. I doubt the distro is yet optimised for the new chipset but browsing was night and day compared to RPi1.
On RPi1 I did not bother with box art and all that fancy catalogue stuff but with RPi2 I think I'll make an effort for a richer XBMC experience.
