Thinking of buying a new mini iPod? According to ThinkSecret, Apple is secretly working on the next revision of its iPod mini. It is said to have a higher capacity hard drive (5G), updated firmware, and may add or change the colors it offers. Apple is expected to finish this project by early February, but we won't hear about it for a month. The same article talks about a 5th Generation iPod, which may appear until the mid 2005. It is said to come in a silver enclosure and not the classic white case. Mmmmm.... I wonder if this will open the door to different colors for iPod Gen?
