SonyEricsson announched that the Xperia X10 is upgradeable, but the said the same for the P1i, but this one, also with the latest update, still has many of the bugs and issues the M600i has (I owned them both).
I'm sure that for the X10 will be different, but after 10 years of Ericsson and SonyEricsson phones and smartphones I've changed brand; I don't know if SE will be able to regain my trust, I just hope that they learned that a smartphone is not a blender and it needs software updates.
