Flash 10.1 Beta 3 spreads the hardware-accelerated H.264 video love to more graphics chips, specifically some decidedly less beefy netbook chips: Intel's GMA 500 series and Broadcom's Crystal HD video decoder. Stick with 720p Flash video, and you'll be dandy.
The Broadcom Crystal HD chip is a video decoder chip you'll find in newer Pine Trail notebooks, like HP's Mini 210, while the GMA 500 chip is in a ton of notebooks, from Dell's Mini 10 to Sony's Vaio netbooks and others. Congrats if you made it this far without immediately flipping to Hulu to check out how much peaceably your machine runs with Flash 10.1. [Adobe via Netbooked via Engadget]
