for me it's the best windows phone up to now
it has 4.3", fits perfectly in my hand, it's an OLED screen (I really don't care about the PPI, it's perfect for normal usage), it has a microSD slot since I have a LOT of music and it has the specs for all apps (1.5Ghz and 1GB RAM). For me, these were the important points for buying it, and I didn't regret it.
So far, I find it great. Especially the camera which is outstanding. Maybe not as great as 920, or the Symbian 808, but is better than what is needed for most regular users.
