I don't see how the reader software needs a persistant wireless connection, my kindles don't. I never use it with my desktop version and never with my reader except for a couple times when I just wanted to try things out and I have had Kindles since only a few months after the introduction of the K1. Plus there is the Wifi device now as well which could go months w/o a web connection.
As for incentive...there is no less incentive to make a version for Pocketbook devices than any other handheld device. And if some sort of wireless connection is a MUST have then maybe a version for only the readers with that ability. The software should be connection carrier agnostic and wifi is obviously sufficent.
And the whole store front thing would just seem to be a browser based deal meaning the device would need some sort of, hopefully, webkit based browser which are already out there...then just hook into that when needed.
I see there being some tech hurdles but to my thinking it would be a way to expose the Pocketbook brand to a huge existing market segment. Of course I also see it as potentially competing with the planned Pocketbook ebook store so that might be difficult to deal with...should Amazon pay Pocketbook for content purchased from the Amazon store via a Pocketbook device? Dunno how it works on Apple devices.
I was thinking the hardware and OS would be fine just needing a nudge here and there for the OS quirks...
To me a Pocketbook reader that had the Kindle reader software and the other existing software would make it THE best of all worlds reader because it would truly handle almost everything out there ebook wise. And that could only be a good thing for the brand.
Still if it does not work politically then that is business and nobody's fault, just life in business.
btw, don't take my response as bing argumentative in a negative fashion...just stream of consciousness discussion of the idea. I understand there are potential hurdles but wonder out loud how to over come those issues. so I enjoy the discussion and reasons why it might not be reasonable to see done.
