If you'd done any product research before buying, this would be no surprise. The N900 is a computer first, and a phone second. What do you think of its functionality as a handheld finger controlled PC?

Now Nokia has already announced support for portrait mode in certain app, and developers can implement it in their third party apps as they please right now.

MMS support should come later, but isn't very simple. It took Apple 3 years to add... I doubt Nokia takes as long, but to be honest, there is no announcement for adding it at this time, which doesn't mean they won't, just they haven't told us. Same for speed and voice dialing. There are Contact shortcuts, however, something no one else can offer.

For file sending, try Petrovich, which is available via the App Mgr. Same for a voice recorder. If months to add a feature is long to you, your expectations may be insatiable. Who else is implementing features in months? Android? WinMo? Apple? WebOS? Didn't think so.

As for phone features, this is an area where Nokia has unmatched experience and expertise. I doubt anyone in the industry questions Nokia's ability to develop the phone features. I'm least worried about that area. You have an old Communicator so you know as well as I. Do you fear Nokia will fail at the phone's development, its core competency?
