I do not exactly agree… In my 18+ years of Wacom experience I have encountered loads of applications that needed extra configuration or plainly would not work at all or with caveats (one of the reasons why I quit using Messiah:Animate on a dual screen setup). Have you tried to use Cinema4D without changing settings when using a tablet? You’re in for a surprise - the view goes crazy. The problem with most programs is that one cannot change the basic settings in combination with a tablet - Blender 2.5 will provide in this, which is great in my opinion.
As long as a user can choose his/her own individual settings in Blender 2.5, it’s fine. One user’s preference may not be another’s. Who is to say which control method works best? Very much an individual’s preference. What works for you may not work for me. I couldn’t care less about whether an application delivers a default Wacom control scheme if I cannot customize it to my liking. And don’t forget: even Wacom’s control panel gives you so many options to change stuff. For example, I hate working in ‘mouse’ mode, while other people I know swear by it.
No, I am afraid it is a bit naive to expect every program to work without a hitch with a tablet. There are too many variables.
I have to say, though, that I love 3d-Coat’s tablet control scheme - click in empty space: rotate view. Click on object: sculpt. Mix this with the modifier key control, and it’s bliss. No needlessly pressing of keys and very fast. I would really like to have an option where one can just click in empty space to control the rotation of a view pane in 2.5.
And yes, I do agree with everyone that the <alt> key should work regardless of whether one selects to emulate a three mouse button or not.
