a problem you likely won't have, if you have a tablet-computer, is latency

I tried a wifi tablet once, but no joy.. can't get my head round the stroke appearance on screen lagging behind the physcial action, even by a small amount; and it makes sound sync a bit of a nightmare; maybe why my cintiq pro does not have the option...

parallax on the otherhand [offset of the line from the stylus point] is something to watch out for



in the tub some devices are water resistant, or claim to be; my samsung phone is pretty good in that regard, can take pictures under cold water, never tried hot and don't intend to... anyway i much prefer a shower...
