I've just got my XS to replace my (stolen) Desire S running CM9 (ICS).
Picked this device in part for its distinctive stand out appearance (much the same reason I did for the Tablet S). It does feel s little clunky in the hand, though sure I'll get use to it - but build quality feels way over & above the S3.
Thought I would miss ICS more than I do - though looking forward to getting it back in next few weeks hopefully!
Bit annoyed with the level of un-uninstallable pre-installed apps - managed to get rid of a few of them like the sat nav software - but can't get rid of officesuite viewer - even though i've installed OfficeSuite Pro!
Overall though - very happy so far.
