So, had the intel imac about two weeks now, gettting pretty used to it. One strange thing that DOES seem to be like the windows world, is an apparent interface slowdown with certain users. MY user, I have setup mail and moved some files over, put about 20 songs in itunes and done some simple configuration to the preferences, brightness, mouse setup, etc. Interface startup, login, etc is still fast mind you, no real complaints, But, now the OTHER user I setup for the GF, I only setup her mail, haven't moved any of her files over, haven't setup itunes or iphoto. And the startup is just FAST FAST FAST, and using the interface it just seems a lot faster. REAL fast. I know in windows, the user files, desktop, mail, my stuff etc as it gets big, it makes things slow down, but I didn't expect this here and certainly not this quickly with such small adjustments.
