The full article, which I came across through today's Shelf Awareness link, was featured in this morning's Telegraph, and is worth the read.
The most interesting bit, I found, was the possible threat to Amazon's market share that successful iPhone/iPod apps could pose. Any thoughts?
I myself just got an iPod as an early birthday gift (THANK YOU) and it's already loaded down with audiobooks, e-book apps and reader apps... I could see how this multi-functional device could easily pose a threat to the uni-tasker Kindle (especially given that the Kindle is only compatible with Amazon products).
