The ebooks really are frustrating aren't they - I blame this mostly on apples iBooks though which is best for novels really.

We're exploring digital travel guides over at coolplaces.co.uk and are busy building out content (uk only for now). So it's interesting to read your ideas on this as they are close to ours. It's early days yet for us, and we have a lot of ground to cover before we get to custom travel guides created by users, but it is on the roadmap, and these are exciting times to explore travel info. Would be interested in your comments on our site.
