Just picked up two of the Roku Streaming Sticks +.
I hooked up the kitchen TV last night...easy to install, fast searching, loading apps...pic quality good...idk if it's the same dual core processor that's in the ultra, but I think I'm taking the other stick back in favor of the Ultra for the loft TV. We're 100% streaming now for TV and this set is the furthest from the modem/router.
The one draw back in the rigid stick design...your wall mounted TV must have side mounted HDMI ports or sit off the wall several inches.
