Of course, what really matters is the games, right? Luckily, Microsoft has a pretty strong launch lineup, with some of the regulars like EA's The Sims 3 and Need for Speed, along with some exclusives like Rocket Riot and the hotly anticipated The Harvest. The good news? Games look and play great, just like you might expect from an iPhone or Android level capacitive touchscreen platform, with The Harvest as an obvious and very important standout in complexity and polish. The bad news? Everything takes forever to load (our rough estimate is about three minutes to start playing in The Harvest), and when you don't have any multitasking, that's a really bad thing. Check out some of the Xbox Live hub and capabilities after the break, along with some games, and make up your own mind.
Update: We got some bad info from the rep in this video: you can view Achievements earned anywhere on the Live service, including games on mobile, the PC, and the Xbox 360 -- that's what we thought! Also, as should seem pretty obvious, the Avatars are being live rendered on the phone.
