basically my main computer is a windows 7 pc, my laptop is a new mac book air, i want to buy a logitech g710+ mechanical gaming keyboard, the keyboard will be used for gaming but also so i can type up my essays for college on as its a nice typing keyboard, so i want to know whether i can use the parallels software to run the keyboard as the keyboard (like most mechanical keyboards out at the moment) is not compatible with mac OS but it is compatible with vista win 7 and win 8, and also if i was to say buy microsoft office for mac would i be able to use it on the windows partition? im not quite sure how the file sharing works regarding that and i dont know how much space this is going to take as i only have a 120gb hard drive with 53gb left over after 2 days of use :/ thank you for your time and i hope you can help!!
