Raise your hand if you were underwhelmed by Google Talk not only being Windows-only, but a desktop app. ::raises hand::
I'm sure I'm not the only one scratching my head over Google's decision to do a desktop app as opposed to a web client. It's not like it hasn't been done before — AOL's AIM Express is, as far as I can tell, a pure DHTML IM client although I can't tell for sure if it's a persistent connection or polling. Actually, I don't care; AIM Express rocks. It does the job, works in Moz, 'nuff said.
Most likely Google Talk is chained to the desktop due to it's VoIP features. Fair enough, I don't think, uh, VoIP-over-HTTP is a worthwhile endeavor right now. Maybe the IM features are just a nice-to-have thrown in on top of an app that was initially designed to make VoIP as easy as IM.
But still, kind of a strange sideways move for Google.
