If you have a router all is fine. If not then I vote for wireless if you don't want to run wires/cables. With the encryption now adays, you don't have too much to worry about. There is also nothing hard about setting up a wireless network. I have 4 computers on my wireless network. One is running Win98SE (The primary computer connected by eternet to the router.) A desktop running WinXP, A Laptop running WinXP and A Laptop running Win2000. All can see each other, print to central printer and surf the internet.
