Amazon has found a relatively clear day in the calendar on which to launch its excellent Kindle Paperwhite e-reader in the British Isles. The ad-supported basic model will knock you back £109, while an extra £60 will get you the 3G version. Amazon's Lending Library service will roll-out at the same time, offering Prime members free loans from a collection of 200,000 books as part of the £49 per year subscription (which also has other perks). If you're shopping around, don't forget that Barnes & Noble's equally glowing alternative is also available in the UK these days, wearing a pretty much identical price tag.
