OK, I don't have 7 yet but its released to the public I'll be one of the first in my area to get. Now, when I do get it how hard will it be to network my three OS'?. One pc has xp home, mine has vista home premium and my new one will have 7. Not sure if I'll go retail or build one. With vista and xp home it took some doing, about an hour of downloading ltdr and configuring. I was just wondering if any you others (LOST) had the three OS's networked and what was envolved in doing so?
