Not sure on WinMo7 but they better do something, being that RIM is basically done and will go the way of the dinosaur
I think it's premature to say that RIM is done, but certainly they have alot of dead inertia on their platform and they have only recently added long overdue features seemingly in direct response to the Android "explosion".
MS, with Exchange, still has a massive corporate presence they can piggyback off of with a truly innovative integration to their mobile platform. They have a great opportunity that they have been squandering year after year. Now that people have a variety of next-generation smartphones to choose from, (I hope) consumers will be looking for more than just pretty UI from MS's next WM release.
As a business customer, I want to know what the hell they are doing with Office and how this will integrate into the cloud and mobile market going forward. Some of my users still don't have integrated Outlook tasks and notes syncing, I am confused why I must dedicate scarce time and resources training people to learn MS's new "ribbon" interface, tons of time and money is being spent doing legal discovery from their ancient Outlook PST file format, and Exchange continues to be expensive to maintain and support.
It irritates me to no end that MS has ignored these needs for so long, and quite honestly makes me question anything they claim to be promoting as their "vision" for the future...
