Apple has pushed out new developer betas for iOS 4.2 and iTunes 10.1, the former coming two weeks after the initial beta, and the early impressions are apparently far more positive. The software adds multitasking support to the Apple slate, as well as wireless printing and homescreen folders; however more importantly it's said to be much more stable than the first beta.
You can download the new betas at developer.apple.com, though of course you'll need a developer account with the company first. Apple has previously confirmed that the iPad will see the iOS 4.2 software update in November 2010.
