If someone is amazed by the new iPad that Apple announced today, but recently bought an iPad 2 from an Apple Store, is it too late? Could that person return the previous iPad purchase in order to be able to buy the latest and greatest? What options are available for someone with buyers' remorse?
The general rule is 14 days to return things, but I would just go in and let someone there know your concerns. Also, there often are price reductions which would make your recent purchase less costly if that was something you preferred to have.
If you are past the 14 day Apple return policy you can try asking your credit card company. Some, like American Express, will allow you to return merchandise for a longer period.
