i may get the 27'' with i5 3.1 or maybe the i7. i already have mbp so it is not my first mac. first,i want to install windows 7 on bootcamp to play some games (and some future games),how much size you suggest should i portion for windows ? second,i have some vidoes,sounds and apps which i want to transfer to my imac. do you think it is better to install windows when i first get my imac before i do something else ? and then transfer apps and videos ? and finally : can i print documents by connecting wirelessly to another pc (windows 7) which is connected to a printer ?
