Wow, amazing how much difference a year makes. Even I have just bought myself a Kindle3 (although as a publisher I do feel kinda dirty now ). I started using the Kindle app on my Android phone, then Kindle on my laptop. I also tried Kobo on by phone and PC. In the end, much that I hate Amazon, I had to admit that, in terms of the software and storefront, Amazon really do have it sussed.

An analogy is with the various MP3 players competing with the original iPod. Why did the Zune tank and iPod reign supreme? I reckon it's about the software and storefront, i.e. iTunes. It was such a no-brainer in terms of buying and downloading tracks. I found the Kindle is to iPod as Kindle Store is to iTunes. Right now, Kindle is winning hands down, although Apple's iBookstore is catching up with respect to sales volume.

Google has really fumbled and have delayed launch until next year.
