Google just announced movie rentals in the Android Market at its I/O conference. Chris from the Android services team just hit the stage at Moscone and demonstrated renting movies on the Android Market from your phone, tablet or PC with a single click. "Pinning" mirrors the experience with apps and books, you can select it on your PC and download to the device in the background for offline viewing. Movies are live in the market right now, support on all Android 2.2 or higher devices is expected "in a couple of weeks" and tablets will get support bundled with their upgrade to Android 3.1. On the PC, it ties back to the recently expanded YouTube rental service with the same restrictions (30 days to watch, 24 hour window once you start watching) and pricing, making that per-movie VOD price a bit easier to swallow with its cross-platform support and we even spied a few HD selections for $4.99. Keep an eye on the liveblog for more information.
