My brother recently replaced his dead Prism with an old Best Buy floor model of the N710c.

He wants to know:
1 - What is the best free/extremely cheap way to get the Sony to work with his Mac OSX Powerbook?
2 - Is there any way to get AvantGo to work on OSX? If not, can he run AvantGo in OS9?
3 - What are some must have games/programs that take advantage of the hi-res screen? (he has actionnames already, btw)
