This is embarrassing, but I'm wondering if I'm the only one who has ever done this. I was reading a paperback version of book on parenting (I'll be a dad soon,) and I came across a word I didn't recognize. I actually started to touch the word with the intention of seeing the definition magically pop up.
Needless to say, it didn't work.
Also strange is that I own a Kindle 2, not a PRS...so I'm not even sure why my brain thought my pBack book was touch compatible.
