I'm still waiting for something that fits my needs: great hardware with NO INTEGRATED 3G...or at least not something that I have to buy on contract. I just want the hardware, not a monthly contract to go with it.
I can't ignore the ecosystem aspects either; I've purchased at least 50 apps for my iPod Touch, and being able to use those on an iPad is a compelling advantage.
I'd say there's a 70% chance I'll get an iPad 2 when they come out...but I still wish they did a 7" version. That's the size of tablet I'd prefer.
