Hi Dennis.
The new Surface should do even better that the W500 I think
Surface Pro should run rings around it.
I posted this over on KORG FORUMS you might like to watch.
http://www.youtube.com/watch?v=lhPpVqxEOEkTurns the Tablet PC into a free V-Machine. Handy if your looking for a host that doesn't have to be touched during a live gig.
I also had a W500 some time back, not too shabby a unit really....issues with the touch screen operations but pretty good nonetheless..
Yes the touch screen used to stop responding for a few seconds. Had that problem too. It would happen a few times a week. Just leaving it alone for 5 to 10 seconds it would start working again.
Since installing Windows 8 I haven't had that problem since.
Regards
James
