I've noticed that many people are not happy with a tablet. I think the reason may be that some are thinking the tablet replaces a mouse (which isn't necessary). A tablet, in best practice, is really just a tool, best used for specific tasks. I've used a tablet for over 10 years, but only for specific tasks and I don't use it as a replacement for my mouse. I use the tablet exclusively in Photoshop, mainly for retouching and restoration. For me, the only reasons I use a mouse is for the pressure sensitive features, and, in a lesser degree, a better sense of control when making selections. If neither of those are something you use on a regular basis, I wouldn't recommend forcing oneself to adapt to a tablet.
When I first started using a tablet, it took me a while to find the best settings, that most closely matched how I was using a mouse. These are my current settings (found in Control Panel)
