Thanks for the eideticker effort. I hadn't heard of that.
I've subscribed to several key performance related bugs already but haven't seen much movement with them.
What's more worrying is that there doesn't seem to be much talk about improving responsiveness. Originally the goal was to perform better than android with lower-end hardware but that effort seems to have been tossed aside.
Lastly, there is the whole design issue, which corbet was kind enough to delve into a bit in the review.
