Who Needs a Kindle?
I've been reading a lot of books published by Amazon Kindle, but I refuse to carry (and pay for) another device. I've been reading books from Kindle on my iPhone, and it works great for me. Yes, you end up flipping pages a lot, but you can make the font quite large, and it works great for me. Recently, Amazon also released a Kindle app for the PC (Mac coming soon). You can download the free app here: http://www.amazon.com/gp/feature.html/ref=kcp_pc_mkt_lnd?docId=1000426311. I've tried it, and it works great, syncing the current page with my iPhone, so I can flip back and forth between devices. With a tablet PC, this would be a killer app. I do wish you could print pages directly from the application, but I understand why you cannot. On the other hand, armed with any screen capture utility, you can capture and print individual pages quite nicely (which I'm doing at this moment with the free "Cook's Illustrated How-To-Cook Library" that I have in my Kindle library.
Will I read books on my PC? Probably not. But I'm far more likely now to buy technical books from Kindle than I would have otherwise, and to be honest, I'm pretty tired of buying technical books in dead-tree format. On the other hand, you can resell a physical book when you're done with it, and you cannot with a kindle book.
