A thorough review on e-Ink touch readers from Marco.

But Instapaper on Kindles isn’t perfect. I’ve been able to generate newspaper-style navigation that works on all non-touch Kindles, but the Kindle Touch and Kindle Fire use new periodical-navigation formats that I haven’t been able to successfully generate yet. I don’t know if Amazon will ever make this possible. And recent changes to Kindle “personal document” storage makes it difficult to delete old Instapaper articles from the Kindle Touch.

I don’t actually see any issues with its performance of Kindle Touch. There’s definitely a lag after clicking home screen, and opening a new book, but otherwise page turns are reasonably fast for me.

However, as pointed out, the lack of periodicals support and being unable to delete/archive these documents on the device is really frustrating. I hope Amazon fixes this, along with performance improvements, in the future software updates.
