HGiles: I was in a similar boat, and wound up getting a regular ereader and a tablet. My ereader is small and sturdy enough to go everywhere, while my tablet is larger and has games and PDFs for when I have a sitdown moment. I put everything on the tablet and the mostly-text books on the ereader.
Don't you find illustrations, tables and code (if you read that type of textbook) a pain to look at on a regular sized ereader though?
I already found pictures problematic on a 9.7 inches ereader, can't imagine what it's like on a 6-7 incher.
HGiles: The problem is that competing paper and tablet products are good enough that manufacturers simply skipped larger ereaders. Sony was coming out with something interesting in Japan that had a flexible display, but since they're getting out of ereaders who knows what that will come to. There's also been advances in LCDs to reduce eyestrain, but those are years away from production.
I must admit that except for the eye constraint, there isn't much reason to go for an ereader instead of a tablet at that size.
Still, I'd guess there is a small, but steaby minority of avid textbook readers that would want a 9.7 inch ereader, but maybe I'm overestimating my own demographic.
It's hard to say, because as they are currently feeling neglected by the ereader market, they tend to go for tablets anyways.
HGiles: Most ereaders can read a generic format, and then are locked into a specific bookstore. EX: Kindles can read regular DRM-free .mobi files, but can only buy books from Amazon's store. The solution to getting an epub file onto a Kindle involves cracking the DRM and converting. This is trivially easy, but does required a basic level of awareness and computer confidence. Adobe's upgrade is apparently designed in response to the trivial ease of cracking their DRM.
Imho, any company whose ereaders doesn't support the epub format is clearly more interested in promoting it's ebook store than it's ereaders.
HGiles: The current situation of competing vendor-specific DRM schemes was partially the result of the first Adobe upgrade, where Adobe proved they weren't interested in providing reliable infrastructure for the bookstores. After that, the big players came up with their own DRM schemes.
That might have been the spark, but they were assholes in their implementation.
I mean, Amazon and B&N (for example) could have agreed to support each other's format on their ereaders.
Clearly, their whole stragegy centered around getting a captive market and go for top dog position.
HGiles: Adobe is so irrelevant in the US now that I can only see this upgrade reinforcing the lesson to have an in-house DRM solution. Many smaller ebook sellers are already interested in going DRM-free so they don't have to pay Adobe fees and deal with Adobe's bad customer support. This may push some over that edge, but it will also probably drive some out of business as they have to pay for new servers and handle customer complaints.
I think in some case, they go DRM-free either because of principles or (more likely) because the customer base really wants it.
I mean, O'reilly had the resources to implement their own DRM scheme, but given that their core audience is the IT crowd, I think they figured their clientele would really appreciate being able to freely access their books on any device.
HGiles: Libraries, including openlibrary.org which has many books not available elsewhere, are really going to get shafted. They have neither the technical expertise nor the money to deal with this. They may well not even be aware of it. But they're going to be the front line when Gramps has a problem with his ebook checkouts.
For sure, implementing in-house security mechanisms has always been a big player's game.
Smaller joints usually resort to third-party solutions given the experize and testing man-hours required to get it right.
