I’ve had my Nokia Windows Phone Lumia 900 for a couple of weeks now and I have to say, I like it way more than I thought I would.  Just like many of you, my company uses Microsoft Office and the new Lumia 900 has absolutely flawless integration with Microsoft Exchange, Outlook, Word, Excel and the rest of the Microsoft Office suite.  Web browsing in 4G on its 4.3-inch, AMOLED screen is an absolute pleasure and the phone is made of a very tough polycarbonate plastic that feels great in your hand.  If you’re a gamer, you’ll really like the Xbox Live integration and the Windows Phone 7.5 operating system is growing on me. And, for you geeks out there, while the Lumia 900 looks underpowered on paper, I was delighted by its speed and power.  If you’re a Windows person, for $99 with the obligatory 2-year AT&T contract, this is a smartphone should take a serious look at.
