I have mine veritcal on the bottom shelf of my entertainment center where I used to keep some cds. I also took off the covers and picked up some wavebirds since the Wii is the first Nintendo system I purchased. The second shelf is just above the top of the transmitters for the wavebirds so I don't even really notice them. Very sweet having the system all wireless and in the living room where video games were off limits except for rare occasions!
As far as VC games, nothing cooler than having Military Madness wireless and at my finger tips from the couch. Now if they could take it online, that alone would be worth buying a Wii for.
