I'm considering purchasing an iBook with an AirportExtreme card in it so that i can (hopefully) network my pc and my new mac together super easily and still be super mobile. I was wondering, since I have a cable internet connection and leave my pc all pretty much all the time, how difficult would it be for me to get my mac & windows box to communicate so I can share my internet connection and my files between them from anywhere in my home.
I'm also assuming that I can do pretty much all of this from any standard wireless network card that I just plug into my pc.
What worries am I going to have doing this, and what do I need to get to ensure that it all goes together smoothly so I can just come home from uni with my laptop, open it up downstairs and start checking my emails as i relax and not have to worry about walking upstairs to touch my windows machine at all.
Any suggestions on software (open source is preferred - i'm a poor uni student who likes to code) or articles I should get/read would be appreciated as well as your own tips (to tell you the truth I'm hella-excited to be getting an iBook and can't wait to play with osX).
