Query: So irritated with Amazon

I know this review is going to generate a lot of back-lash towards me, but I am just so irritated with Amazon that I had to express my frustrations somewhere.I have not even had my Kindle for a year, and now they are coming out with one that is better, with a better keypad, better contrast, and lighter weight? I am so irritated that companies don't let consumers know there will be a newer model product in less than a year. You think you're spending your money on something good, and then you find out that "Oh, by the way, after you purchase yours, there will be a better model".Sorry to vent, and hope that this does not generate a lot of backlash. I wish I never would have bought this thing and had decided to get the Sony Reader. I paid over $200 for my Kindle and it is not even touch screen. WHAT WAS I THINKING?
