Yeah, my initial order was back in the early days (4 March) and I just kept getting responses to my queries that "a new production just came in and we will be shipping yours next week." I'm sure it was chaotic to do such a launch, as popular as it was, so I'm not really complaining. When they offered the X7 and confirmed the specs, I was happy to change. I use a stratus (for position also), so my only requirement was the wifi. My older tablet was 8" and I would have preferred larger, but brightness was the main thing.
Back when I ordered, the 4g X72 was only $550 vs $500 for the X7, so price really wasnt a factor. They seem a little disorganized, but I'm not really sure they are set up to be a primary seller. Great engineering, needs work on follow-through. In the end it all worked out, and I pretty much forgot about the $50 refund until it showed up 6 weeks or so later....
