Yeah, there were a lot of feature grids and checkboxes presented as evidence to the impending failure of the iPhone when it was first introduced, apparently nobody learned from that.
The WePad looks like a fun device to tinker with, and I see potential for resellers or commercial use, but it's not playing on the same field as the iPad (yet).
That's very subjective. It's true though that Apple has been able to sell products that generally have lower specs then their price equivalent. But if that is because of marketing, killer applications, user experience or something else isn't really clear. They're definitely not dominating any market based on number of devices though.
What I'm most curious about in the tablet space is if Linux, with Android, MeeGo, Chrome OS etc. will be able to shine. As many tablets will be ARM based, there will be less competition from Microsoft. With a decent distribution platform we might see a situation where developers will be able to reach more devices with Linux than with iPad/iPhone OS. Especially from a global perspective.
