It occurred to me this week that I have now had my Kindle (keyboard, WIFI) for just over 500 days. In that time I have charged it up from a flat battery no more than 10 times, whilst using it for an average 45 minutes a day. Pretty impressive battery life.
Also, while I have a couple of hundred books on the thing, I have spent less than £10 on Kindle titles from Amazon – there is a remarkable range of PD ebooks out there.
