I reserved one for in-store pick-up. I figure I'll get the $499 wifi only model for a few reasons.
1. Its the 1st gen and I don't want to spend more money on a device that if I like it, I'll be upgrading next? year.
2. See #1 - this one will get passed to my hubby when I get a new one.
3. I plan on using it like a big, phoneless iPhone, if I need 3G, I'll use my iPhone
4. I think I may prefer the HP Slate if the lack of flash becomes bothersome--I'm always on Facebook
5. I'm already in negotiations with the hubby to get a new HD Tv AND a Wii. I'm getting the hairy eyeball on the tech spending.
