Whatever you did with your Amiga before but faster Run games/sw you were not able to run before, like lantus360 mentioned, there are some nice ports out there. ScummVM will give you some nice games too if you like that genre. The best usage of course would be to use it to program some new sw for Amiga.

throw all your other computers away and start using your Amiga for all your computing needs.

Netsurf for the internet is all you need. What could impress your peers more than turning up to important meetings with an Amiga 500 in tow, using Scala MM300 to perfectly illustrate your new marketing strategies to your area manager. "This guy thinks outside of the box" they will say, and that big promotion you've been hoping for could be closer than you think.
