Continue to battle with Asus Eee Slate (EP121)

After reading a few forum post, I reignited my passion on fixing a few problems that I had with my Eee Slate so far, including:

• Bluetooth keyboard and mouse frequently got dropped for no good reason.
• Not able to join Homegroup 
• Stylus not calibrated properly.

At least I got the homegroup problem fixed by installing the wireless driver Version  Version V10.0.0.110 .  THis is the latest one (2012.10.30  update),

And then I installed the bluetooth driver Version V8.0.0.206.  Again, it's the 2012-10-30 update, which seems to be the best I can get.  I am now using my bluetooth keyboard and mouse.  It;s see if it can survive for the rest of the day without dropping.

The digitizer problem, though, is still not fixed.  I tried the hack mentioned here.    At the end I give up, which kind of once again prompt me to think about buying another machine.  Damn it, I just so frequently wanted to spend spend spend.
