Should you have the impulse to turn your dumb display into a full-fledged Smart TV, LG has revealed the second iteration of its Smart TV Upgrader box is ready to hit the marketplace. The original ST600 box was released last year, and this new SP820 was announced earlier this year at CES. It adds LG's Smart TV experience complete with Magic gesture and voice controlled remote to any HDTV with an HDMI input. There's access to both 2D and 3D streaming content from the internet, DLNA, Wi-Fi Direct and any new apps LG rolls out for its platform. Similar to Apple's TV box and the Roku family, it's a palm sized device intended for easy installations. An even smaller, stripped down SP520 version that supports fewer apps is already on shelves with a $120 MSRP, although sale prices range from $80 to $99. The SP is shipping in June for 199,000 won ($169 US), while there's no word yet on a US release, we'll probably wait to see if LG can add enough apps to compete as a third party before jumping in.
