I've been using e-ink readers since the early days of the first model Sony introduced internationally. I've also owned a first android-based nook which I've had really high hopes for, but in the end I converted to Amazon, mostly because:
1. Hardware -- at the point I converted it was superior to competition.
2. Wireless delivery (and not just for myself, but the older relatives who can't figure out online shopping but learnt how to use a kindle).
So the ecosystem came bundled with that.
While I have nothing but praise for the Amazon CS, there's plenty not to love about amazon as a company. How about
:
1. In the early days they were caught on displaying higher prices on books to registered/logged-in users than unregistered visitors to their web-site. Because you know, once you're suckered in, you'll pay a few bucks more.
2. The way then lean on kindle cover manufacturers and strong-arm them into paying outrageous royalties -- a few times higher than any other product sold thru amazon retroactively 6-12 months after they've agreed to a normal percentage.
3. From what I hear from people who worked there -- nobody is irreplaceable attitude toward the employees.
