I've had a Wacom Bamboo for many years and bought a new Wacom Intuos last year. I can't scrap without it.
My Bamboo was a pen + touch one, my Intuos has only a pen because I never used the touch option. I actually use it for everything. I have a laptop so it has a trackpad, and I do use that for when I'm typing and I need to move the cursor just slightly, but for everything else I always have my pen in hand. Browsing, scrapping, whatever. I never get a mouse-hand or whatever you call it.
I can't remember it being awkward or difficult in the beginning but that might be because it was long ago. You should really get all the functions work the way you like them to. That takes some time though. Oh and there is a click-thingy on my pen. Click forward is left click and click backwards is left click. Easy peasy. Plus there are buttons on the pad? I never use those though.
Oh and I have it on the right of my laptop, at an angle. I cannot work with it if it's straight.
Don't give up on it! You will so love it after a bit!
