is the pre worth it?

I haven't had a chance to play with the hero yet, but I could make an argument for either device. The one thing that kept me from waiting for the hero is the lack of a physical keyboard. I can't type on a virtual keyboard for crap. Since you're coming from the touch then it may not be as big of a deal for you.

Android has more apps at the moment and is a more open platform than WebOS. It's also a bit more mature since Android has been around longer. The hero supposedly has superior battery life to the Pre.

It's all a matter of which device fits your needs better. Both devices are very good.
