Now this one has buttons, that would be much easier to use so I might look into this too.
This is mainly personal preference, but I have an Intuos Pro M. The thing has 9 buttons, and a little circlepad and yet I've never used the buttons sans one of them as an Undo key.
My old Bamboo was a bit better in terms of button performance because it was just 3 buttons, and they were nice and large.
So while it may have a lot of buttons, you might not end up using them at all, and just try to keep that in mind.
