You left out part of my claim.  The big "always-connected" selling
point, and built into the very desktop of the phone, is the continuous
updates from Facebook, GMail, and Twitter.  My claim was that when using
these kinds of features that talk to the server every few minutes, that
the battery life was jokingly short.

Right now I'm studying, but I hope to do a full post on my Backflip
findings later tonight.  In the meantime, I'll note that just yesterday,
an AT&T-compatible version of Nexus One became available (from Google;
AT&T isn't selling it yet).  Not that I'm likely to get one.  I don't
see Nexus One beating the iPhone with such poor marketing.  The Google
page on the phone doesn't even list what applications come on it, or
show what they look like, what the on-screen keyboard looks like,..  For
an interesting comparison, see

As my cranky old AT&T 8525 (HTC TyTn (not TyTNII, but upgraded to
Windows Mobile 6, which is as far as it's going to go) starts showing
its age more and more (and it's just barely acceptable now), it seems I
am being forced to give up a physical keyboard, which is the only
barrier left to me getting an iPhone now that they've advanced to the 3Gs.
