Is 6.5 to stay as Microsoft's enterprise mobile platform?

I am currently on a developer meeting by Motorola here in Tel Aviv and one of the messages brought by the key speakers is a very interestibg one: while Windows Phone 7 is a new product that will focus in the consumer market and compete directly with the iPhone, MS is totally committed to the continuatiom of Windows Mobile 6.5 as their enterprise platform, and Motorola/Symbol is buildimg its plans on that.

My thoughts on this option just after the break.

I believe this is quite a logical move, at least while WP7S cannot provide features needed by enterprises for their apps, and while the chassis requirements don't match the needs of enterprise mobile terminals.

However this move will perpetualize (at least for the next years) 6.5 side by side with 7 and make it the default OS for mobile terminals. Additionally, the OS would still be available to whoever wanted to build a phone based on it. And I am not sure that this would be of Microsoft's best interest.

As I see it, it would be best to give WP7S business edition the important missimg features like multitaskimg and copy/paste, the appropriate APIs and SDK for enterprise applications, and make it more flexible in terms of chassis to permit the use of WP7S in mobile terminals and as a consequence the use of enterprise applications at regular busimess oriented phomes. This would make the terminals more useful to workers, the phone more relevant to management, and everything easier for developers.

While I can see the permanence and continuation of development of WM6.5 as a temporal solution while 7 Business is not ready for prime time, in my humble opinion Microsoft should strive to make this situation as short as possible.

WP7S is a clear move to make Windows Phones more attractive to the consumer. But should it be done on account of the business users?
