Hi there, I'm considering buying my first Mac (Macbook Air) and am wondering whether it is possible to set it up in a way that allows me to do the following: - Run Windows through virtualization software and use Microsoft Office (especially Excel) in it. I know this is possible, but how smooth and fast is the experience? Is there any time lag (e.g. when typing)? Is it possible to set up a shortcut in Mac OS that directly brings up the virtualized Windows Excel? - Use all the standard Windows keyboard shortcuts for Excel (Do all the Windows shortcuts work on the mac keyboard? I'm a Excel Poweruser and need them) - Have the virtualized windows software access all the files I have on my mac (is this a problem due to different hard drive formatting?) Configuration questions: - Should I go for 8GB or 4GB of RAM? (Mainly office work, sometimes foto editing) - How much space will be left for actual use when I choose the 128 GB drive? (After Mac OS plus Windows 7 virtualizied) Thanks a lot in advance!!
