I use the trackpoint on all three of my ThinkPads, plus the trackpoint on the external UltraNav USB keyboard I got to use with flatdell and with my main thinkpad when it's sitting on the dock.
Beyond that, the mighty mouse is okay for Macs, I have a lenovo bluetooth mouse, and I really appreciate the slightly older style Dell mouse, the one they used from about 2004/2005 to 2008. I've got two of them (one optical and one not.) and haven't ever had problems with them.
Wacom tablets are great, but still pretty expensive, especially if you don't do much actual work with graphics. In my experience it makes photoshop work go more easily but it's not really necessary, unless you're actually using photoshop/flash/illustrator/another-graphics-app as a medium for drawing.
