There’s been an annoying issue with the touchscreen on the U810. If you don’t use it after a certain amount of time, maybe 10 seconds, it takes a second to get the touchscreen to respond again which makes inking frustrating.
I noticed the UMPC Portal forums, rexibaby posted a link to a comment in an Amazon review showing the solution to the response issues.

After using the u810 for a day – I also became frustrated with the unresponsiveness of the Touch Screen after not using it for 10 seconds or so. It was so frustrating to me that I was beginning to consider a return. Fortunately I finally found the solution so I thought I’d share.
HERE’S THE FIX! (Instructions are for Vista Home Premium – might be different on XP)
Open up “Device Manager” in Control Panel.
Expand “Human Interface Devices”
Double Click “FCL USB Pen Tablet”
Choose the “Power Management” tab
uncheck “allow the computer to turn off this device to save power”
That’s it. Real responsiveness! This really makes a HUGE difference in usability. Even if you have gotten used to the way it works or you’ve never had another tablet so you feel it’s performing ok – try this.
I tried it out and it works. The touchscreen is much more responsive now. Happy inking!
