5G iPods, PowerBook Updates?

ThinkSecret posted some blurbs about potential updates to both iPods and PowerBooks.

Regarding iPods, ThinkSecret mentions that upcoming Mini models could hit 5GB capacities, meanwhile the 5th Generation iPod, due in mid 2005 at the earliest, may move away from the white form factor to "a more silver enclosure".

PowerBook supplies have widely been reported to be constrained... but ThinkSecret feels that PowerBook announcements will be made soon -- possibly on Jan 25th or Feb 2nd. The site reiterates their previous predictions of 1.5/1.67 GHz models.
