I purchased a Lumia 900 last week and have thus far been more than pleased with it except for this one thing: absolutely no Bluetooth Keyboard support whatsoever. It is difficult to overstate my disappointment with that considering the otherwise excellent Microsoft Office integration. This is doubly odd because nearly all iPhone and Android devices do this while Windows Phone 7 devices do not, and because this feature existed in the older Windows Mobile releases. Windows Phone 7 users have been waiting for this to be implemented ever since Windows Phone 7 initially rolled out according to the websites I have read. It was widely hoped 'Mango' would add the feature but it did not. As much as I love the phone, I believe Microsoft needs to be called out on this by a major publication. If Windows Phone 7 is to succeed in a business environment, basic Bluetooth Keyboard support is essential.
