Seagate GoFlex looks nice on the paper, still I don’t really believe in them. Their main objective is to sell HDD-s. True good media player is very much about software and constant development. It's about community and customer feedback. In these areas are guys from Seagate, WD and Dlink not so good. I personally had to thow away one WD Live and one Dlink box, because of their bad UX, incompatibility with some HD MKV-s, poor sound quality and sluggish UI.
But We’ll see….
