Just back from Sam's Club. In the tech aisle they now have the WDTV Live on a cardboard blister pack for $95. Lowest price I found googling was $109 shipped. This is,of course, the new one witht he ethernet port for network viewing, as well as the USB port por playing from USB devices or connecting a wireless USB adapter. Does 1080p video beautifully!
I bought mine in November at Best Buy for $120, and love it! A great replacement for an aging original XBox running XBMC.
In case this isn't everywhere, I was specifically at the Crestwood, Mo store. Doesn't appear to be on teh Sam's website yet. Also saw 750gig ($99) and 1TB ($149) pocket USB powered WD drives.
