The Nokia Lumia 900 Challenge is complete, and all things considered, Windows Phone has a champion on their hands. The Nokia Lumia 900 has some great features like strong wireless connectivity, great battery life, and a killer build quality, but Windows Phone lacks some features like true multitasking and a strong app catalog. Still, for $99.99, you can't go wrong with this device. If Microsoft gets a few more of these high-end $100 devices under their belt, they'll be very successful.
