I'm not really thrilled with pinch-to-zoom. If it's continuous zoom, it will be hard to fine tune the zoom on unresponsive eInk, right? And if it's discrete zoom, you're just bypassing the zoom button, which wasn't hard to use before, I don't think.
I'm actually a little sad -- the 950 is my favorite reader and I kind of hate to think that when it's gone/broken, I won't be able to replace it with the new Sony 7". Since, you know, there won't be one.
