The Pinnacle PCTV USB Stick that you may have grown quite fond of over the past year has finally decided to get with the times, as the newest iteration throws HD capability into the minuscule tuner while still ringing up a penny under a Benjamin. The Pinnacle PCTV HD Stick steps it down a notch from its Professional sibling, but still allows users to "view live television on their PC with pause, rewind, and fast-forward timeshifting functionality." Pinnacle's latest USB 2.0 tuner is "about the size of a key," gets all the necessary juice right from the USB port, supports NTSC and ATSC broadcasts, and comes bundled with the firm's TVCenter Pro software. Best of all, this no frills portable TV tuner can get live programming on your laptop or desktop right now for a mere $99.99.
