Yeah, one of the issues is that noone is really pushing the limits on what ereaders can do.

There are incremental updates to be sure. I recently looked at the Kobo Glo as an upgrade to my Kobo Touch, then decided that it wasn't worth the price. Both devices present the same books in the same way. The only significant difference is an integrated light. The thing is, lights can be found almost everywhere: ceiling lights, lamps, clip-ons, flashlights, kerosene lamps, candles, etc..

Vendors really ought to look at ways to make their eink readers more competitive with LCD tablets. There is plenty of room to do so, and still have a dedicated device. A great start would be better PDF support, as well as supporting alternative formats (such as DjVu). What ever happened to introducing colour? Even washed out or over saturated colours would be a bigger upgrade than an integrated light, and still useful for books. Better title management, since people are loading tonnes of books on these critters. The list could go on. Just look at the wish lists that have been posted on these forums.
