Slightly less convenient, for sure - but for me, this is outweighed by the factors of (i) not having to lug multiple heavy books around - especially after you've finished them but you haven't arrived home yet (ii) always having your book with you (my PDA is my mobile phone too) so you can dip in and read whenever hiatuses in the day appear  (iii) the ability to "search" on words in an eBook, so you can quickly find a passage you wanted to refer to.

However, the format is so prone to piracy that only works in the public domain are feasibly and legally available so far.  With the much-forecast death of the conventional publishing industry facing us, however, eBooks might be a format whereby works of minority interest - viz musicology etc - could be distributed effectively for a nominal fee.  I can't begin to list the number of times a work of study has interested me, but then it turns out to cost 50+ pounds + delivery, so I skip it.  (And no, we don't have English-language libraries covering the outer stratosphere of musicology where I live).

Didn't see this post Ian, but I've started a new thread here.

Until my last PDA expired I used to carry odd, but occasionally useful ebooks around on it, mostly for reference, but as Reiner says, the field is pretty much limited to public domain material, which isn't a problem as far as I am concerned as there are so many books that I feel I ought to have read but was too busy with teenage angst.
It took me a little bit of getting used to using buttons to turn pages (I can't stand having the text scrolling as I read), and a small screen, but it can be done.

Currently reading "Tommy" by Richard holmes, and interesting history of the First World War.

Will soon be reading the latest Harry Potter - just how soon depends whether I or my wife gets to it first.  If I manage to I'll probably be able to finish it in a few hours (I've always been a fast reader).  If she gets to first I'll have to wait a while.

how about that... my wife is a doctoral student in film/media theory, and Rotman is very big indeed in certain subcircles of those fields (anyone who doubts the profound ghettoization of the modern academy would do well to reread that sentence a couple times!).  She handed me this book knowing of my interest in perspective; Rotman apparently has carved out a niche as a leader of, not quite humanistic theory of mathematics, and not mathematically-inflected cultural/literary theory, but something in between.  This book makes much of the imprint of the semiotic subject in the cipher of '0' as a fundamental distinction between the 'iconic' Roman numeral system and the 'syntactical' Hindu one, alongside the gulf between Gothic art (iconic) and Renaissance perspective (syntactical/subjective/semiotic) and also between barter and paper currency.

If you're into that sort of thing (which I am, more or less) it's really very interesting.

Cos then we'd have to get rid of one later on.  We've already 2 copies of some the earlier books as their publication predates "us" (if you see what I mean).  Bookshelf space is sadly limited 9and there are no more suitable walls to put them against (except the one that's earmarked for a piano eventually).
