This is why the BlackBerry--showing steady growth at 19.3 million users--so hard to displace. Windows Mobile usage is up now, was down previously, and appears to be holding steady. BlackBerry .

Windows Mobile's stagnation supports Tony's "life support" argument. However, before looking at the recent ComScore numbers, I'd long ago given Windows Mobile up for dead.

I don't routinely follow handset market share so, for me, having more than 7 million Windows Mobile users seems like a great customer base to grow from.

There may be rough times before Windows Mobile 7 arrives, but the difference here is that Tony sees the glass as half-empty, where I see half-full.

However, I think we'd both agree that a late 2010 release date for Windows Mobile 7 is as late as can possibly be acceptable.
