as bob dole suggested .. depends ...
back in the bad old days, with a prs-505, I used pdflrf / paper-crop / briss etc to attempt getting useful copy ... It (they, in various combinations) worked ... maybe 70 percent of the time ... text only .. no problem .. boxes, boundaries, tables mostly not
so now I use mostly k2pdfopt to reformat books on a lowly pandigital 6" thingy ... works ok for my use ... Thing is, you've got to experiment ... Set a "Standard" and try various options/programs/formats and see what works for you .. IMHO stock answers like "ipad" "tablet" are less than useless ... in particular since you specified (I thought) e-ink, not lcd ... are there any "ipods .. tablets" that do e-ink?
End of rant ... mostly
