I would like to see some new versions for Mac OS too, that area seems to be very very quiet. iPhone I am starting to give up on, I have been asking for over a year and not even seen a screen shot.
Seems to me that Seesmic is very Windows-centric. That's just the impression I've gotten over the past year or more. OS X is an afterthought, and that carries over to the iPhone despite its cross-platform nature.
I agree, us Mac users are starting to feel that Seesmic is moving away to Windows. But at the end of the day it is up to Seesmic to decide if we stay with them or move on elsewhere. Not having an iPhone version of Seesmic is a bad idea. But I am not a CEO so what do I know :)
