PreCentral got its hands on a leaked webOS 3.0 emulator that shows off the first beta build. WebOS 3.0 will run on HP’s TouchPad coming later this Summer. From what we see in the video and the screenshots, the operating system is pretty impressive thus far and is very user friendly. Since this is still just the first beta emulator, you can expect some changes before its public debut. Hit the jump for the video showing off all the new details.
