Amazon have resisted the tempation to trash the battery life by introducing colour screens to display content the essence of which is monochrome. While I am not a fan of the rights-management policies used by Kindle, a device with a decent battery life is very welcome, especially nowadays when ‘process’ has taken us from mobile phones that went a week on a battery charge to devices that struggle to survive a day.

Seems to me that colour screens on mobile devices are like banking bonuses – a self-indulgent luxury with no value to ordinary people.
