According to MacSlash, Apple is offering customers waiting on an iPod mini the opportunity to upgrade to a 15GB iPod at no extra charge. “The demand for the iPod mini has been incredible,” reads an e-mail reportedly sent out by Apple. “We are shipping them as quickly as possible, but we cannot meet the ship date we previously estimated for you… Your business is very important. If you would like an iPod sooner, we are offering to replace your iPod mini with a 15GB iPod at no additional charge. This model usually ships within 24 hours.”
