While I haven't ever read Made to Stick: Why Some Ideas Survive and Others Die, I recognize the book as a brand around the idea of these "sticky" concepts.
I have tried reading books on my computer screen before, and I have been disappointed. Mostly, I have realized that scrolling sucks. Given that I have already paid to download a few technical books as PDF, I needed a reader that could make the PDF experience easier than Preview or Adobe.
Still the best camera of any "smartphone". AT&T or T-Mobile should really start carrying these things...
