My older generation Kobo would be much more useful to me if it would simply do ePub in landscape, so that code samples within texts did not extent past the right margin with no means to scroll. Or if they could be made to wrap, ugly as that might look. Supposedly, the firmware that the Kobo firmware is based on, does this, and some have successfully supplanted the latter with the former. Take this along with the long-anticipated, now increasingly manifesting -- or publicized -- security failures of various "closed garden" phone/tablet environments, and I am increasingly disinclined to use, depend on, or support any such environment that is not open source and therefore amenable to some very common-sense functionality, by the community if and when the manufacture lets us down. P.S. The Kobo firmware is at heart more or less Linux (although based on an intermediate party's customization of same). I'm frustrated at some things that Kobo has failed to offer, but at least there are ways past this (that don't even involve "jailbreaking", in its more legalesque meaning).
