Ed,
I've got the following devices on my wireless network:
1 5yr-old Compaq laptop
1 Work Laptop, Lenovo T42
1 WII
1 Audiovox Maestro PocketPC
1 Palm Treo 800W
1 Nintendo DS (when its rendering pages properly)
1 Brand new Compaq Laptop (Shhhh, don't tell anyone, but its a Santa gift to me

)
The rest of my network amounts to three desktop computers connected by CAT5.
As my friends tell me, I am not an IT person, I only play one at home!
