Had never heard of a kobo till all the posts this week. I don't know what their back up is, I've got (well almost!!) a Kindle for Christmas (except they won't let me have it yetsmiley: ohwell) From what I've been told and read, if I was buying one myself I would go for the Kindle, it seems to have proved itself, and apparfently it's one of Amazons own with excellent support xx hth
i would go read some reviews Sue and see what you think xx
