Apple customers like Roger Cheng have (until now) slept soundly knowing that any Apple product purchased is the "latest and greatest" for at least one year. Today, Apple killed that notion.
Considering the fourth-generation iPad offers relatively incremental upgrades, not all iPad owners will be peeved. However, if you know you'll lose sleep over the iPad you purchased less than one month ago, you're in luck.
After reading this tip from Twitter user @TubbyEmu, I did a little sleuthing.
@sharonvak @karynelevy Apple Care rep confirmed to me iPads bought within the last month can be exchanged for the new one!
