I'm a little disappointed by the responsiveness and accuracy of the alpha switch 12 when I'm using a pen for it. It seems to perform worse than my $300 thinkpad 2 I got a few years back. Here's a comparison: http://imgur.com/a/Td2jg as you can see, it seems like the switch alpha 12 draws more jagged, and it's harder to be precise and circles are harder to draw (like it's harder to close a "g" or an "o" off). Is this expected behaviour (because that would suck) or do I need to return my pen? Are there drivers I can download that might improve performance? I can't even find the driver page for the switch alpha 12.
