I had a Wacom Bamboo Fun tablet for years and LOVED it! As stated before, it certainly can take some time to get used to, but if you use it as your mouse whenever you use your computer it'll become second nature in no time. Now that mine is no longer working (had it for over 6 years!) I miss it terribly! I've found that it makes graphic design work SO much quicker.
I would certainly agree with the Create version for anyone who wants to do more than just sign documents digitally. That's the one I'm planning on acquiring for both pleasure and business, seeing as it's the most economical price for a great product that most probably wouldn't be able to distinguish in quality from the Intuos5. I've used the higher grade tablets, and I can honestly say I wouldn't pay more for them. They feel exactly the same to me.
Also thanks for reminding me to put this on my Christmas list!
