As far as "confusing and boring" I think that depends on the implementation. I've been using WinMo8 for the last 6+ months and there have been a few gotchas but for the most part, the interface is a lot easier to use than iOS6. Although I think that has more to do with the UX and not the UI. I love apps that TapBots make but I don't have the patience and artistic talent to create interfaces like that. My developer hat says it's definitely a lot easier to program apps Flat, but it's very easy to do it incorrectly. You're not alone, but now that Apple opened fire on Skeuomorphic design [1][2] and lots of people look to Apple as design leaders, I feel like you're going to se a lot more flat.
