it's cheap and easy to do that upgrade yourself. Access to the RAM is as easy as removing a small cover on the bottom of the Mini, and 8GB of RAM is only $76 plus tax and delivery from OWC Computing. That's more than enough to run either OSX or Windows 7 through Boot Camp. As long as you're not running demanding applications on either platform, 8GB of RAM should also be able to run both OSX and Win7 with a virtual machine application like Parallels.

But if you need more RAM than 8GB, the costs ramp up in a hurry. For example, 16 GB of RAM costs roughly twice the price of a starter Mac mini -- $1147.99 at OWC Computing on Aug. 11, 2011.
