I am happy to read that you will get a graphic tablet!
Here are some thoughts and things concerned to my graphic tablet.
I am glad you bought one really, because as I am not able to use Seamless with my tablet, I know, for sure, you will certainly fix its behaviour asap for yourself!
The "drag3dSensitivity" function on "Settings" will not work as expected. It is almost like it is not there or it is useless. I already wrote you about this in one of my last comments but since you were using a mouse at that moment you didn't pay too much attention to it.
Resuming: any small movement with the pen will bring a bigger movement to the cursor inside Seamless, meaning not be able to work as expected (as in Blender, Cinema4D, etc), and controlling the movement of my pen in order to have some work done in Seamless soon revealed to be of too much work for just a simple task. Hope you will get it by yourself.
Another thing about working with a tablet, you will first need some time to adjust yourself to work with your tablet the first time. Not because of the issues related to Seamless/tablets but even using a different program, for instance a painting program, you will need to "learn" how to work looking at your own monitor while you are drawing on the surface tablet at the same time. A couple of days will be enough. The most difficult part was to learn how to draw straight lines properly...
I have heard very good things about the multitouch in Wacom tablets. No comments here. For all the multitouch technology, I have to use shortcutkeys in conjunction with my pen buttons
"See you" next time
