So now that you have used both, if you could go back in time, would you pay $499 (original list price I believe) for the Touchpad?
I was questioning the value of my iPad at that price before ever looking at the Touchpad. For the value a tablet, any tablet, brings into my life, I don't think any tablet is worth $499 to me. So the answer is no. But that's with knowledge gained from owning an iPad and seeing what and where I'd use a tablet.
However, I think if the Touchpad had been in the $249-$299 range, I would've paid that. That made $99 a no-brainer.
If I was buying my first tablet and didn't know how I would use it, I admit that my inclination would've been towards the iPad. It's the big name, the leader of the pack. So the Touchpad would have to be priced lower to capture my interest, that's all there is to say. If the iPad and the Touchpad were both $499, I'd buy the iPad. But having bought both, having used both, as I said my Touchpad is used regularly and my iPad is soon to be sold to my cousin.
