The version 3 is amazing . This is what Kindle should have been on the launch. NO complaints whatsoever. Also I highly recommend to get the Kindle cover with LED Light from Amazon. It is simple indispensible. With the cover I was so immersed that unconsciously I tried to change the pages by hand like book one or two times.
Dont but the power supply though for UK or any other country. You can use any blackberry or lastest HTC phone charger ( They have higher capacity thena required by kindle)
