If you don't have a blu ray player now - this unit has built in wifi as well as an ethernet port
Units lower in price than this one usually dpn't have built in wifi -- just ethernet port. You have to spend another $100 for a wifi dongle.
Remember -- at this price point -- the bulk of the price is for the blu ray player -- not the speakers.
I know it's not the best or even that great of sound. I just want a 5.1 blue-ray home theater in a box system that can also do netflix, something compatable with the bluerays and lasts a long time and sounds pretty good for what it is.
