Tablet vs. Mouse

Students are always asking if they should get a tablet or stick with a mouse…obviously this is an individual decision and has a lot to do with personal preference and particular fields in design.

But I wanted to start a thread where people can post their preferences, explain why they prefer one or the other, explain pros and cons from experience, etc. to help others make an informed decision.

Please respond to this thread if you specifically prefer one or the other, which brands, and why.
Thanks!
