I understand Microsoft Office is available to put in the apple machine. I haven't tried it yet but am assured by the apple people I will be able to use all my past MS Office stuff.
Mike,
I use Office (mainly Excel) on a daily basis on both platforms and frequently transfer files between them, with no problems. However, the menus are different and it can be very frustrating, trying to find menu items on the version you are not familiar with.
I've been a Mac user from choice for over 20 years. I also use Windows and Linux at work. These days, for personal use, a Mac is clearly superior to a Windows machine. I have a Windows partition on my MBP in order to use a couple of specialist Windows-only programs, but it runs W7 and I have no plans to ever upgrade!
Moateair,
Yes, the new MBP looks very nice and I might be tempted. However I would miss the matte 17" screen on my 2011 model.
