I have owned this machine for a week now and when i bought it it came with Windows Office 2011 for mac which was useful to me as i was told its 100% compatible with windows office 2007 which is part of my college course. i own an iphone 4 and bought and ipad 2 which i absolutely treasure, it all started with me buying an ipod touch and has progressed from there. Since owning mostly apple products i decided that i would opt for a mac and chose this model and so far i have been extremely impressed with the speed, most notable boot up and shut down times...mere seconds! for an ex windows user i was shocked.
Also the new Intel Sandy Bridge i5 processor is a leap from the i3 and the i3 is still amazing. The resolution is astounding when watching video and looking at photos, 2560 x 1440 i think, and that is HD x 2 so you get crisp images and games look sharper. I know alot of PC people dismiss the mac when it comes to gaming but i have a few games that are pc/mac compatible and they run fast and with no problems. This is my first Mac and i have alot to learn but i think Mac OS X is amazing and super fast from what i've seen from windows 7
If you are thinking about buying this. It is expensive but you get what u pay for.
