It’s been three days since Tim Cook unveiled the new iPad, but you’re still stuck with your trusty old iPad 2. You’re keen to get rid of it so you can buy the new one, but you forgot to log in to one of those buy-back sites before Wednesday’s launch. Predictably, the announcement sent trade-in values plummeting—before the launch, some of these sites were offering close to $300 for your entry-level iPad 2 (the 16GB Wi-Fi model), provided it was in “good” condition.
Pretty clever...
