[Updated -- due to overwhelming demand, offered prices have been adjusted] Sites that offer to buy users' now "previous generation" iPads are still offering good prices for used first-generation iPads, varying by site but offering up to $600 depending on models and condition, the money from which can be used to buy the just announced model. Among other sites, Gazelle.com and NextWorth.com have specifically posted prices for good-condition iPads. Some sites will "lock" offers for up to 30 days to ensure time for the new models to arrive in various places.
