Networking Windows 7 Desktop and Vista Laptop

I am always on the go, doing same work on 2 different machines. If I could figure out how to sync the two computers so that the files I am always emailing back and forth to myself to keep both machines current, then I would probably sync instead. So, for the life of me, I cannot get my Vista Laptop, to share with Windows 7 desktop. Can someone point me to a simple step by step tutorial? I feel I have tried everything, but without help, I keep spinning my whels and ending right back where I started. I use a wireless router, and 80% of the time the laptop is used wirelessly, and the other time, I plug it in to the router.

Oh, and if anyone has a simple sync tutorial, I would appreciate that too!

Thanks again,

Jordan

What are you using for email? If it's MS Outlook it has a built in synchronization but any new email you open, and read, on one PC will not be available on the other unless it's been fully synced prior to reading it. Other useful sync options is Xmarks for PC to PC sync.
