Greeting, I am wondering if I can use the MX700 Duo on the Mac Mini. I just bought another one (By error, thought my old one was dead but it's not) and I'm planning on buying a Mac Mini tuesday afternoon. I was reading the manual when I saw that you can plug only 1 USB connector (And not plugging the mouse into PS/2). I'm not sure if I'm reading correctly though. Any input on this? Also, the shop where I will buy my Mac Mini is offering me to put 512MB of RAM (Which I will do) but I'm wondering what I can do with the 256MB that was built-in the Mac? Thank you!
