"Nice BD playerwith terrible wi-fi networking"2.0 starson by bengrimm99
Pros: User Interface is easy to understand and setup of the unit took less than 30min
Cons: Steps for registration of the unit and various online applications not at all explained. Once you're finally connected to the Sony Bravia content network, good luck returning...the network settings constantly need refreshed and even that doesn't help some
Summary: I tried with 2 consecutive S580's and got varying degrees in signal strength (from the same location a 30% difference)...when I could get the machine to connect to online content, it was great, but getting to that content through the reputedly cheap internal wi-fi card and Sony's BRAVIA network are major hurdles. I'll be returning this one for money back.
