My main problem is the pen jitter, and for that problem there are no solution (after 5 months), and when i adress the problem with the technician they seem to not know what i'm talking about.
When i draw slowly the line isn't perfect it is really wobly and ugly.
And the pressure levels are insane to work with, i have a 12wx cintiq that is supose to have the same specs but it works millios times better in everything.
If this problem do not get fixed quickly, this is my last go at microsoft, i'm turning mac user once i sell this crappy equipment.
People i fount the only solution is to sell the SP4, and buy a Wacom companion 2 or the new wacom mobile studio.
Both of them are far superior to the SP4.
After a year there is no excuse for not having a fix for this problem, and worst than that there is no single reply from MS support in adressing this issue.
Good luck to any artist that bought this piece of .... and good luck.
