There is ONE MAJOR thing......and its THEE major thing about 10.5...........a matter of fact it is a turning point for me finally accepting Macs to have reached Amiga closeness as possible:
PUBLIC SCREENS aka SPACES.
This improves Prodctivity by like 1000% Now my Mac cant act as fast as I think. This is one if the best things about Amigas....To be able to use many screens with different apps at the same time.
Now you can Run XP and OSX in 2 seperate Public screens Natively and practically. Amazing! Get Parrallels!
