I have Vista Ultimate32bit on one laptop and W7rc64bit on another. Transfering files by cd/dvd or flashdrive was a pain so I tried EZ transfer. Setup was easy, picked my files to transfer to my W7 machine via wireless 802.lln. Well, it took 6+ hours to transfer 16gig. Plus the the laptops could not be used until the transfer was complete. Never again.:nono2: I'll connect via ethernet.
