[alanfish]

Hi, friends,
does anyone try to use wacom tablets - Intuos or Intuos 2?
I am planning to buy one 6x8. So, I would like to ask what the difference between Intuos and Intuos 2 is.....^_^

About their specification,
Tablet Dimensions: 13.5" x 10.2" x .6"
Active Area: 6" x 8"
Pressure Levels: 1024
Resolution: 2540 lpi
Max. data rate: 200 pps
Accuracy: +- .01"
Tilt Range: 50º-60º
They looks totally the same as other. Any recommedation??... ; D
The price of Intuos 6x8 New --> US $100
The price of Intuos 2 6x8 New -> US $250.

Thanks for your kind attention.
