Decent, if somewhat flawed review of the Glo. Some comments I wrote over there:
1) The Kobo Touch has 2GB of system memory, with 1GB available for storage of e-books. (
http://www.kobobooks.com/touch_tech ) This is the same as the Kobo Glo.
2) The home page shows your last 5 books, not your last 4 (as shown in one of your pictures above.)
3) On the Touch, you can scroll "off the page" to the left or right when zoomed in on a PDF to show a bar with an arrow icon. Pressing this allows you to turn the page while staying zoomed. I would be deeply surprised if this functionality no longer exists. Did you try this?
