I’ve ordered this list by strength of the companies:
Kindle:
– International and is very aggressive
– hardware has WiFi and 3G
– has the most eBooks
– has exclusive eBooks
– offers lots of free eBooks
– uses proprietary eBook format
– uses proprietary DRM
– designed to lock-in Amazon customers
– setting up an account is easy without a credit card
Sony Reader:
– International but moves slowly
– Killer new hardware in the 350 and 650
– lacks wireless in 350 and 650
– uses ePub eBook format
– uses “classic” Adobe DRM
– can borrow books from public libraries
– designed to be as open as possible
– setting up an account requires credit card
– setting up an account is easy without a credit card**
Kobo Reader:
– International and aggressive
– hardware is cute and now has WiFi
– proprietary eBook format
– proprietary DRM
– can use ePub eBooks
– can use “classic” Adobe DRM
– can borrow books from public libraries
– designed to quickly gain Kobo customers
– setting up an account is easy without a credit card
Barnes & Noble Nook:
– US-only and Chairman doesn’t use his own product
– hardware has WiFi and 3G
– uses ePub eBook format
– has proprietary variant of Adobe DRM
– Nook ePubs can only be used on Nook hardware
– free eBooks are for Nook customers only
– can use ePub eBooks
– can use “classic” Adobe DRM
– can borrow books from public libraries
– designed to lock-in Barnes & Noble customers
– setting up an account requires credit card
Of these four, I think the Barnes & Noble Nook will be in trouble. Both Sony and Kobo understand that being widely available internationally and cooperating on DRM is in the best interests of their customers.
**Apparently Sony made a change since I tried years ago. Today I was able to set up an account without being asked for any credit card information. Not only that, I could download a free eBook too!
