Regarding live tiles, they are really slick and do help get over missing webOS notifications. Do a little research on the current 15 live tile limit that MS imposes and what that means for your phone by combing the forums. Not all live tiles are created equal is the issue.
Just in case anyone's curious by the way, that live tile limit only applies to tiles that use the "Push" live tile method (the one that updates a count number and the tile title text). If apps use the "Pull" method where they grab a new tile image from a web address according to a schedule defined by the developer (most frequent possible is hourly) then they don't count towards the 15 tile limit.
For an example of the pull tile if you're in the UK, check out Lawrence Gripper's 'BBC News Mobile', works very well and is free (and no I'm not affiliated with it at all)
