Samsung from Japan ?... seriously though... I have a GN12.2 and Gigabyte p34w v3, and use both extensively for my architectural design, the GN for sketching, engineering apps and phone, the p34 for 3d modelling, realtime rendering and presentations.
Now, if you could blend the two I would be in tech heaven..
PS, I have not used pen and paper since getting the GN 12.2... the pen technology is brilliant and should be standard issue to any designers...
