I am also looking to upgrade from a Clie, an SJ-22 in my case. I like both the N810 and the Touch, though I will miss the one-handed operation and jog wheel I now enjoy. On the other hand, the new pricing on the Touch is rather tempting. I wonder when the next Nokia is due out to force down the price of the N810.
As for the question of e-ink, my commute just got a lot longer, but I now have WiFi for most of it. So I while I expect I will still read a lot, I also want a multi-function handheld that can do the web/email thing and waste time with the occasional game or video.
Another device to consider, depending on your needs and your time frame, is the Open Pandora project (
www.openpandora.org), which is designed for gaming, but runs Linux and seems to have a lot going for it. I expect the huge battery required for 10 hours of gaming will provide for plenty of reading. I almost picked up a Zodiac a while back for the same reason, but they discontinued it just about the time I decided on it.

The Pandora is not released yet, but since a new machine is not in my budget just yet, I am content to wait and see.
Good luck with your choice!
