Luxury book publisher Kraken Opus is now selling a new special-edition iPod touch, the Prince Opus. The player is provided alongside a book of photographs of the funk and R&B singer, selling for a considerable $2,100. Only 950 units of the iPod are being made available, whose exterior features a purple front, and a back with a laser-etched Prince logo.

Special pre-loaded content consists mainly of 21 Nights, an exclusive concert movie taken from a series of performances at the O2 Arena in London during 2007. Also present is a live soundtrack from Indigo Nights, consisting of 15 songs. The offerings are diminished next to those from branded iPods sold by Apple itself, such as a now-defunct U2 iPod which contained the band's entire record collection.
