I installed Virtual Tablet app (
http://www.sunnysidesoft.com/) on Mimas and linked it to my laptop via wifi. It worked!!
This small app lets you convert your stylus supported devices into a digitizer graphic tablet. So I gave it a try in Mimas. It worked well for me. But it is still a bit clumsy because you can not see your drawings on the mimas screen but only on the PC screen. So maybe not suitable for serious graphic works, but good to use as a fun addition.
And I like the Mimas support service offered through their emails. They replied and kept the conversion alive until my problem got solved (dictionary support for a single word in PDFs). That is a good sign!
