It seems that James and I just can't agree as much anymore on mobile platforms and I just can't let his post titled, "When will the current version of Windows Phone be the one that matters?", slide by without a response. The post states that the "Lumia 900 is leaving reviewers less than impressed" and I have to say that is not what I am seeing online. If you look at the excellent review roundup on GDGT you will see that the average score of reviews online, 26 reviews are counted, is a very respectable 8 out of 10. User reviews show 9.3/10, but users don't yet have it so I don't put much value in that score.
As I posted in my own review the Nokia Lumia 900 is one of the best Windows Phone ever and it will do well in the U.S. Jason Hiner from ZDNet also spent some time with the Lumia 900 and stated in his review, "With the arrival of the Nokia Lumia 900, Microsoft’s Windows Phone 7 has pulled even with Android and iPhone in many ways, as I’ll explain." I laughed when I read Jason's take on the display and how he thinks it is great since so many people online seem to think the 800x480 display is inadequate.
The Nokia Lumia 900 is a very solid device, but it doesn't beat the iPhone or Android devices on specs and the latest and greatest features. However, Windows Phone is better optimized for mobile than the other platforms (never that you could say that about a Microsoft product, huh?) and doesn't need the highest end specs. At $100 or less, I still believe the Lumia 900 will sell like hotcakes at AT&T stores.
