Version 2.0 of the BlackBerry PlayBook was a significant upgrade — enough that we decided to re-review the tablet — and now RIM has issued another, much smaller update that should fix a few of the niggling issues with the operating system. While no features have been added, PlayBook users can expect to see better browser performance, improved Android app support, as well as optimization fixes for video chat and the BlackBerry Bridge app (which lets you connect your PlayBook to your BlackBerry smartphone). Of course, the update doesn't fix all of our qualms with the tablet, but the fixes should be a welcome change for regular PlayBook users. Version 2.0.1 of the PlayBook OS is available now as an over-the-air update.
