Yes, that is the one. Let us know how you like it. I purchased it on Oct 24 but returned it soon after due to the problems they later fixed with the most recent FW update.
I will eventually be purchasing 2 more streamers, 1 for downstairs and 1 for the bedroom. If the ff/rw and playback problems are fixed I will go with the WDtv. Nothing against the kdlinks but I don't need the HD bay and the 700 is more money. Plus the interface and apps are much better on the wdtv. Also, it shows metadata info (artist, runtime) while browsing. You have the play the movie to get the metadata info (NFO files) on the KDL. The WDTV has iOS/Android apps, is hackable with custom themes, and has a longer proven track record. WD is not going out of business any time soon.
All in all, none of these fancy things mean squat if it won't play my files flawlessly. If I had to choose then it's back to the kdlinks and I'll be happy.
The wdtv streamers use the Sigma chip.
