Well, I finally performed the OS upgrade and tried it out. Very nice indeed! I'm still not big on stylus control though. Good for strafing, but the Axim is hard to hold while manipulating the buttons with only one hand. You need something to prop the right side (top) of the unit against while you play in order to get any kind of useful gameplay out of it. A thumb stylus would work great here.
While I'm at it though,
v0.02 has been released.
I've updated the OP, too.
