One thing that really, significantly helps with this is transcoding to JPG with a small Gaussian blur. From my testing, adding "-guassian-blur 0.05" is invisible to the naked eye and reduces final JPG file size by 1/3 to 1/2, everything else being equal. Right now I have... 72 complete manga volumes taking up about 5.5GB on my ONE, or about 75MB per volume. Not too shabby, IMO.

And at least for me, going from ~4GB (Kindle DX) to ~8GB (Aura ONE) is a big improvement in storage. YMMV of course.

Kobo really needs a better PDF solution. The Sony Reader PDF software on the PRS-600 kicks the Kobo Aura One up and down the street, even with a processor ten years older and maybe a third of the RAM.
Yeah... but if you normalize against the rendering resolution? PRS-600's CPU is 2-4 times as powerful as Aura ONE's. But seriously, it's not entirely CPU. The software is a significant factor. Aura ONE certainly has the chops to handle PDFs but Kobo haven't put the effort into optimizing the reader software. On the other hand, Sony have put a great deal of effort into optimizing their PDF software.
