The most important USP
Can you throw it at your annoying mate who is spouting some crap about immigrants and telling you there's such a thing as "Britishness" without a single hard fact to back up his assertions, pick it up, store it and then find it in a drawer seven years later, not only with enough charge to power up to prove it's worth charging but also fully functional?
If the answer to any of the above is "no" then it's not a bloody Nokia. And don't get me started on fixed batteries. I still have devices that use BL-5Cs long after the handsets that created the format have gone from the market.
