Amazon made the announcement at a big launch in the US, where the Kindle Fire has been a smash hit. Sadly, the Kindle Fire is yet to arrive here, and there's no word on UK release for the products announced today either.
The Paperwhite goes on sale on 1 October, costing our US chums £75 or £112 for the 3G model. The current Kindle gets a slightly better screen and is now cheaper too.
Sigh. looks like I will be waiting a while.
