Yes, I am very, very, very, very, very, very ticked!!!!
I would have preferred that Google waited at least a year before bringing any enhancements to the Nexus 7 (preferably two years), and even then that they still charge the same amount for the old version, and much more for the enhanced version. That would be the only fair thing to do, would maintain or enhance the value of my investment in the Nexus 7 (that's why I bought it, as an investment that would grow in value over time), and would be a fantastic business model that would attract tons of new customers for Google and keep them very competitive in this always stagnant tech industry.
So yes, I am ticked, and not just a little! Damn you, Google, damn you!!!
