Actually I get pretty respectable connectivity with my iPod Touch. I have an N router (D-Link DIR615), but have it throttled back to b/g. I use my iPod Touch to listen to streaming audio when cutting my lawn... all 3 acres of it!
The router is located in my "man cave" where the red arrow is pointing. The property is roughly 350 feet front to back and side to side. For the most part, it almost never drops out.
