I seem to get hangs if I stick my Z in the cradle too soon after un-suspending (which is effectively what you're doing by un-suspending in the cradle). I've not had this problem since I started waiting for a little while (5 sec or so - the time it takes for the backlight to come on and the highlight to start moving on the screen) before placing my Z in the cradle.
there are still a lot of bugs that need fixing
Perhaps, but nothing which I would consider a show stopper. In fact I can't think of a single bug which affects me off the top of my head.
