I chose none of the above, since the poll options don't really reflect the two kinds of documents I actually load up:
- eBooks/texts that interest me which I want to read, or at least give a try.
- eBooks/other documents that I have as required reading or supplementary reference or whatnot.
The composition of the former changes drastically according to what I'm interested in at the moment, though it's generally mostly a mix of #3-5 & 7 for my own acquisitions, with occasional forays into #1 & 2 if the library's got them in.
