Different devices in each region wouldn't have been necessary if Amazon followed the Nokia approach and used Bluetooth tethering but then Amazon would have to somehow offer the cut price data plans on existing contracts... and they still somehow have to ink agreements with at least one service provider in each country they release into - a logistical nightmare that could see the Kindle released only in the USA.

The lack of any WiFi connection is also quite bizarre but again it's omission serves only to reinforce the business model. Pretty naff all round really.
