Oh yeah, I forgot about that
But, that is only useful if you have 'net access. Seems a lot of people don't connect their wii to the 'net. Maybe down to wireless and getting that to work can cause grief or the robbing prices they charge for 'official' USB to ethernet adaptors
But, I'd say routers are the big issue, if people struggle to master connecting their computer to the 'net, try explaining routers and wireless/wired connecion and connecting more than one device to the 'net via a router .... its fun, I'm always being asked 'just a quick question' at work, no I'm not in IT just like to be aware of whats going on and if possible why, if I don't know I look and find it out
