Ah Miss Shelf, one doesn't need to read ebooks directly from computers. I read all my ebooks via my PDA. Since I look silly carrying a handbag, I store several books inside my PDA instead, which I can whip out at any time to read. Typically when I get stuck in queues or during transit.
I do agree about the physicality of a book - the feeling of page turning, the smell, the feeling of actually holding a paperback, etc. Reading on the computer is too strenuous for me, but you can still "contort in comfort" with a handheld device. Plus you can read in the dark as well.
Then there's the issue of archiving. If you maintain an account from an online vendor, you'll never lose them at all (unless they close down, that is). They can be backed up and stored. You never worry about loaning. You can do an immediate search of a word you don't know (something I never do with a paperback). You can perform searches and it makes you coffee too! Plus there're so many books you can get free.
What's not to like?
