I'm no fan of Microsoft in general but it looks like they made some good choices here. It's refreshing to see a GUI that's not just an iPhone clone or yet another awkward facelift on a dated product. I think it will be successful. SmartPhones don't have the same level of legacy baggage that prevent users from jumping to another platform easily so I don't think Microsoft is out of the game at all. It'll be interesting to see where their market share comes from. I'm thinking RIM & Nokia more than Apple & Android.
