The Nokia Lumia 900—the hero product from Microsoft’s premier Windows Phone partner — hits AT&T stores on April 8. In advance of the launch, the reviews have come rolling in. Mossberg focuses on the flaws, and while nothing he’s written is inaccurate, I can say as a consumer that I find that the joys of the product outweigh its shortcomings. I will say it loud and say it proud: I love my Windows Phone. I liked the HTC Trophy (awful camera notwithstanding); I like the Samsung Focus Flash (a bargain at $0.99, with contract); and Nokia brings the platform to a new level with more sophisticated hardware.
