Agree about the controls. I know you can adjust the repeat rate or whatever with the directional control which should ease up some of these limitations...but I haven't tried.
It seems like the games could temporarily adjust the settings for the control to optimize the playability. I know that it's REALLY tricky to control Stuntcar Extreme and Solterra. Men have walked on the moon - I'm sure there's a way to solve this problem.
Bluetooth controller isn't a bad idea, but the best thing about a handheld video game is that you don't have to set it down to play it... Especially if you've got a touch screen for DS-like controls.
I'd be way more interested in Bluetooth linking to other devices for multiplayer action.
All of this seems so common sense to me! Microsoft never thought about this?!
