I am very happy owner and user of a Mac mini (Mid 2011). I am enjoying the easy transition from Windows 7 to OS X Lion. I have had few bumps but catching on fast. I have been wanting to get one for some time and finally pulled the trigger to buy it. I have already bumped up the RAM to the max, 8 GB. This system runs smooth and fast. I am using the usb keyboard with mouse right now. I have ordered a track pad. May order the cordless keyboard later on. Using a Dell 24" monitor which is HD. Just overall a very sweet set up for me. Lion is not a bad OS. Has some funny quirky items but I can deal with them. I am very pleased and happy with my choice.
