This poll seems to have some meaning behind it. Still kind of a strange poll.
Anyway, I chose Amazon, just because I assume Amazon would be cheaper, with free shipping and we'd get the same product either way. I'd have to know a lot more about Skritter selling them to answer that in any other way.
The only way I might buy a Tablet from Skritter is if it was cheaper, came with a few months of subscription, or had something unique about it that I wanted.
