For me, ebooks are blimmin' brilliant for reading short stories, flash fiction, poetry and collections. Mainly because I can read them on my phone and take them with me wherever I am. I can fit them into those tiny slots of waiting, for buses, people, work, inspiration.
The other reason why ebooks are amazing is where publishers are doing more than just giving you words on the screen in the place of a page. It's where they give you multimedia. A perfect example of this is when my husband bought 'The Hobbit - the enhanced edition.'
You see, the husbands likes to have a hard copy to read at home and the ebook ASWELL so he can read it on the move, or on his lunch break. With this particular edition, just at a touch of a button you can hear JRR Tolkien himself singing the songs. Did you hear that? He SINGS them. It's magical. Suddenly, those lyrics I often skimmed over, came to life spectacularly. I wanted to link to it, but alas, the brilliant songs could not be found. Go figure.
So I guess my question to you is this: with ebooks looking to stay, should we be looking at incorporating more into our writing that could be explored with multimedia?
