I went through today and learned the tablet I received a few days ago, since I have some editing coming up. WOW. This is probably my best investment overall, meaning saving my arm from RS. This is a wonderful tool and it is a tool, not a toy. I didn't even realize I was avoiding editing because my arm was hurting. Very nice.
For anyone thinking about buying one for whatever reason--do it. You will not regret it. It's fast too. You can make selections with the free form selection tools very precise and fast.
Terrific, aren't they?!? I have used an Intuos for years--on my second one as my first was serial and drivers weren't available anymore. I just bought a small Wacom Bamboo Fun for my laptop also where I don't even do any photographic work (well I may fiddle around a bit when traveling) just for the ergonomics over a mouse. I had/have an old Graphire that I used to use on location but gave that to my spouse a few years ago and he wouldn't part with it---and he tried a large number of mouses (mice?? LOL)--balls, etc.
Then--for editing, I can't imagine not using one. They make a huge difference in what you can do precisely.
