Yes, the WebOS gives another unique experience on the tab and some features are truly fantastic. But, you don't expect to pick up various apps and have fun just like on Xoom.
I really don't think webOS is anything like the old palm 5 operating system. It may be where they were heading with os6 but unless you've had experience with a post Trio palm phone, such as the pre, I don't think there will be any similarity.
