Yeah but that's just the critical mass thing... There's many folk in that user-base that'd be willing to switch... (& hence potentially turn-the-tide in the longer-term)
If nokia had an effective marketing strategy, & could actually convey all the niceties available, should they decide to switch.
But really, Alien Dalvik needs to be part of that strategy as a "clincher" IMO, & it's not gunna happen i think...
