I found that sometimes booting the iLiad with an SD in hung it, popping the SD out and restarting it seems to work. I guess there are issues reading the SD at boot anyway because I *always* need to unplug and re-plug the SD after a cold boot in order to get a dist of files on it.
Regarding the stylus stuff I suspect that's another software issue that needs addressing. When you place the stylus in the holder it's supposed to register that it's there and turn off stylus sensing. If you leave it out for 3 minutes away from the screen, then the sensing is turned off and you have to re-holster the stylus and take it out again to turn it on again.
I've found that sometimes if you put the stylus back in during a page turn or some operation where the iLiad is busy (green light on or flashing lots) it doesn't seem to register that it's gone back in. So next time you get it out (if you've left it longer than 3 minutes) it doesn't seem to work at all, and you have to put it in and get it out again to turn on sensing.
These are annoying little niggles but basically software issues that need tweaking, and we all knew we were getting unfinished system software; I am sure they will all be addressed in future updates
