Its the Milestone in the UK, which is annoyingly slightly different from its US brother the Droid. Seems to be less dev support than the Nexus or Droid for one, which is why I went for the Nexus....
Quite different phones: Moto has a physical keyboard, tough design, Nexus has the raw power and Google backing. All comes down to if you want a keyboard or not IMO, neither will disappoint.
Its been done, won't be anywhere near as easy as Desire ROM -> Nexus because of the massive hardware differences, don't think it's been done on the Milestone, but I could be wrong.... Its the similarities between the Nexus and Desire hardware that make ROM swapping so simple....
whats the difference from the uk version and the US version?
