wow, nice lots of replies.
I see we have a diverse group here of macs and pcs.
One thing I really like, is how easy it is to video chat, screen share, and file swap. My aunt is totally clueless and I was able to send her a file, connect to her computer, put it in the right spot, and open it, showing her how to use it in a matter of about two minutes.
Amazing. Totally beats phone support
Not saying that it's not possible on a PC, but on a Mac it's much easier and more convenient.
