The BD80 is the bare bones unit for what you want. It will do exactly what you state, but the LG is more desirable to many as it is feature laden, particularly the streaming suite. If you are the audiophile that enjoys the mch music formats, then Oppo starts entering the picture. If you don't mind spending the money, you will probably enjoy the LG more. If it was me, I'd just save and get the Pana, because I don't care about streaming.
You want all the streaming via wifi, get the LG. If not, the BD80 can be had for a lot less.
