Is there any software that can help callibrate the screen that is easier and more accurate than the prebuilt options?
yes, it's packed and ready to go
I had an apple cinema display with my pc - 20" - very happy with the look, feels comfortable and faster to work than on 24" and not tiring
I'm only getting extra ram and an external HD and a wireless mouse - do i need more stuff?
i guess i forgot to mention it - i got a mac mini - will be upgrading to 2 or even 3gb of ram - it runs very smoothly - very good and stable system!
