There are virtually no differences anymore between ogg and mp3 decoding. Encoding is so optimized, that ogg can optimize compression by 2,5x (that is 250%), for 80% of the encoding speed compared to mp3.
Tests on battery life on mobile devices have shown that decoding ogg only takes marginally more power than mp3 (you lose less than 18% playing back an ogg file and about equal when plying back an ogg with similar quality).
From hardware side there's no noticeable increase needed to decode ogg.
Concerning ebook, a solid archive would make less sense when the reader extracts each html separate, but even if you select a large ebook, say 70MB, compressed to 7MB (say it has a lot of pictures in it), decoding needs less than 5MB of ram.
Most ebooks are less than 1MB (most of my epub books are about 750kB in size), they need less than 750kB of ram for decoding for solid archives, and I'm reading in 7z, that zip needs at least 2MB even for a 750kb file (don't know if that's true though).
