Starting today, Americans can pick up the very first Xbox Live-enabled portable. Windows Phone 7 is now out in the US, and is available in a variety of flavors. Can't decide which phone to get? Our friends at Engadget have reviews of all the launch devices — international and domestic. Want to know more about the Xbox Live experience? Read our review.

In addition, we also updated our Windows Phone 7 games page, with all the games that have launched in time for the US debut. Which games should you pick up? (Tetris) Which ones should you avoid? (Frogger) We'll be updating the page with one more batch of reviews, so keep it bookmarked!

Finally, Microsoft has finally announced plans to release new Xbox Live-enabled mobile games "each week," with games ranging in price from $2.99 to $9.99. (Doesn't seem like Microsoft is chasing the 99 cent price point, like the App Store.) In addition, Microsoft is promising to future "Deals of the Week" and seasonal promotions — Summer of Mobile Arcade, perhaps? We'll definitely be keeping an eye on how Microsoft continues to expand gaming on Windows Phone 7.
