I have 2 wacoms that I use. You would have to pry them from my dead fingers if you tried to take them from me. If you took them aways from me , i would devote the rest of my life hunting you down and taking out not only you, but the rest of your family and their next of kin. lol.
When you first get the tablet, you will need some time to get used to it, but it becomes second nature and its just so much natural and easy to work with over a mouse. The only time I pick up the mouse was if Im using the older version of cs4 and the cursor bug pops up. I click on the tablet with the mouse and it clears up the pen issue. I use the pen for everything. I am on either a mac pro with dual 23 acd or my mbp and I could never imagine working on a photo with a mouse. the tablets stretch and cover the screens so the movements are contained and more fluid. I find it faster and more efficient. I have a freind that still uses a mouse, and i just scratch my head . Its easier to mask, select, draw, drag, fade, etc, the pressure sensitivity is great and you can tip the strokes and basically have it behave as if you actually had a specific tool in your hand. I can honestly say it is one of the top 5 best investments i made in my setup and I doubt you will regret purchasing one.
