i believe H01 is the 3G version while the A01 is the Wifi only version.

Just bought the XE500T1C-H01 from 1GadgetDotCom last Saturday. Ready stock.
But make sure you check everything at the shop. Turn on the device complete the config and test the touch screen plus the digitizer with the S-Pen.

The first unit that I bought have a faulty digitizer. Touch using fingers can detect but using the S-Pen cannot detect on the left half of the screen. Lucky my house is nearby so just return it back on the same day and 1Gadget replace a new unit for me with no question asked

Updated to Windows 8.1 and I can't believe how smooth this device run with the minimal spec that it got. Still remember using netbook when Intel Atom first came out and that was a nightmare .

BTW what case did you guys use for this tablet. Any casing selling at Samsung outlet?

hmm, that's weird. does the charm bar appear when u press windows key+c? do your touches register at the right side? it shouldn't be a hardware fault if it registers touches.

then its not the touchscreen issue. because if its a touchscreen issue, digitizer also cannot detect. try digitizing your settings fro touch again in control panel-tablet pc settings. configure your touch settings and calibrate the touchscreen and restart your pc and see if it solves your problem.
