So I broke down and paid more . . .
I just bought a 32GB from eBay for $279. Here's my thinking:
I'm on the hp list to be notified when the new production run comes in. However, I suppose there are tens of thousands of people on that list, too. I may or may not get one -- if I do, I can sell it on eBay (or keep it). If not, I expect eBay pricing to continue going up. This tablet will do everything that I need a tablet to do, so anyway you look at it, I've got a good, inexpensive tablet. And, if cyanogen completes the Android OS hack . . . well, so much the better!
