Browser ... online. Topic ... loaded. Tinfoil hat .. reading green and ready. Speculation ... engage!
Anyway. More serious.
I suspect the first half of 2008 will not see much eInk activity in regards to new products. We may see several community or software improvements over the next months though. I hope so.
In the second half of 2008 I hope the software and hardware for current readers will be maturing and become more solid in use, support and pricing. I also suspect eInk prices will gradually lower.
2008 should see at least several new products though and I think connected readers along with connection-aware shops will see a rise.
Fictionwise will almost certainly improve integration of their existing catalog with their newest MobiPocket aquisition and perhaps make some online API for searching/buying akin to Amazon. Would be smart of them.
