I plan use Lightroom 3 and understand that I will need to buy LR3 because I use Windows 7 for my main computer. However, after seeing that the MacBook Pro comes with iPhoto, I wonder if I will need LR3 for the Mac since I plan to import the files from the MAC to my Windows computer. Any issues with this? An NEF file is an NEF file, is that right? Or once it's viewed in iPhoto does it change?

The 15 inch screen seems fine; is there any reason to go to 17 inch?

Will the MacBook Pro come with email capability and something like MS Word or will I need to buy MS Office for MAC?

If I create an MS Office document on the MacBook Pro, will my Windows computer be able to read it?

If the MAC comes with its own Office-type of software is it specific to Mac's or will my Windows computer read it? (Seems unlikely)

Will there be any problems with my Windows machine using the image files that were first imported to LR2 on the MAC?
