Now that Nokia & Microsoft are in an agreement to create Nokia phones with Windows Phone, I'm hoping for more exposure. The first phones announced were not that impressive, Lumia 800, a somewhat rushed job to get a Windows Phone out by the holidays (However their marketing campaign everywhere was awesome!) and the Lumia 710, which is more of a cheaper alternative. The newly announced Lumia 900 does take a bit the 800 but with much more added features. I think the N9 design got a lot of good feedback so they decided to stick with what's working for them and pack it with more punch. Here's an intro video by Nokia Conversations.
Here are the specs of the Lumia 900:
Networks: GSM/EGSM 850/900/1800/1900, WCDMA 850/1900/2100, LTE Band 4 (1700/2100) & 17 (700)
OS: Windows Phone Release 7.5 – Mango Commercial Release 2 (Mango + LTE)
Memory: 512MB RAM
Storage: 16 GB internal memory (14.5GB user memory) + SkyDrive cloud storage
Weight: 160g (5.6 ounces)
Dimensions: (max): 127.8 x 68.5 x 11.5 mm (5 x 2.7 x .45 inches)
Wi-Fi (802.11 b/g/n)
USB 2.0 high-speed
Bluetooth 2.1 + EDR
3mm headset connector
From what I've read and seen, I can say that it's on par with the Samsung Focus S phone. Focus S has a slimmer set. Similar features. Compared with the HTC Titan, Titan packs a bigger screen at 4.7". To put it easy, it's one of the full-featured Windows Phone. Unless there are newer phones from Nokia coming out by Q2 this year, I just might be getting it (need a good GPS)! No announcement on when it's gonna be released here let alone in the US so expect to wait a while.
