You should see one in person. It's a gorgeous design and begs to be fondled. I'm an iPhone user but IMHO the Lumia 900 is the best looking phone on the market, bar none. What I do not like is WP. As a Mac user one would naturally assume I hate all things Windows. But I have no allegiance to a brand or a platform. Whatever works best for me is the tool I'll choose. Right now it's the iPhone. Used to be BlackBerrys. If the Lumia comes to Sprint (I have a ridiculously cheap family plan) and they come up with a modicum of Mac integration support I'll definitely try one.
I'd also say the gap is there to give your thumb or finger a place to "grab" and swipe without accidentally launching something or having the phone recognize it as a long press. It's kind of a "place your thumb on the right side of the screen to swipe left" subliminal message Looks weird, yeah, but I'm used to it.
I wonder if TMO will carry this phone... There were some rumors a little while ago, but they all seemed to quote the same one source too, so that makes them even more unreliable...
That was quite informative,thanks for your review. It is now ten times smarter and organized compared to other nokia phones,It is simple and easy to use.
