The Smashwords blog recently published a post about the increase in the number of people with the technology to read e-books on the move. Mark said:
"We'll probably also see the lines of distinction between tablets and e-readers blur over the next six months as e-reading devices adopt more multi-function features."

I think he is absolutely right, and an article I wrote for Sconul Focus 49 I mentioned the potential of multi-function devices such as tablet PCs and smartphones to really open up the market for e-books:
"Some technologists question the whole point of specialist e-book readers. Does the future of book reading lie in dedicated devices like the Sony PRS, or in more versatile gadgets like mobile phones? [Specialist e-readers] don’t have flexibility of purpose, and generally do not have colour or touch screens... [they can't access] databases any more than they can access subscribed e-books on the major platforms. However, [multifunction devices] can access online databases, as well as being able to display e-books, connect to the Web, act as a communications hub (e.g. for email and Skype), play music and video, even games [...] the number of portable small-format PCs is only going to increase." E-book readers: what are librarians to make of them?
