I am thinking about purchasing a laptop to design on when I am on the move. I usually work on my desktop, but I would like to be more mobile, so I would love to have some suggestions.

Here are some questions I have that might help you help me:

I have always used Windows, but is now the time to switch to a Mac? Is the learning curve that big? What is the benefit of being on a Mac?

Does it make a difference if my desktop is windows and a laptop was mac? I would use dropbox for storage of things so that I could go back and forth between the two as needed, so would it hurt anything to go between the two systems?

How big should it be? I don't have the best eyesight so I want something I can see, but I also want something that is easy to carry and handle.

Thanks in advance for any information/suggestions you have.
