Without getting into specific dates at this time, sources familiar with Apple's Macintosh hardware roadmap say the company is striving to unveil a completely redesigned set of Intel iBook laptops just in time for next year's K-12 educational buying season, which takes place around April or May.
The report goes on to say that the new PowerBooks will be similar to the current Aluminum design but that they'll be "about 20- to 25-percent thinner than today's model." I hope that they take it a step further and introduce a PowerBook nano. Apparently the future of the 12-inch PowerBook is in doubt too, but don't fret because it may get replaced by a 13-inch widescreen iBook.
The new PowerBook is also believed to sport a built-in iSight camera (like the model found in the new iMac) and maybe even a dual-core chip. If Apple ships this beast with a dual-core Intel Yonah chip—which is rumored to be main reason that Steve Jobs chose Intel—expect the new PowerBook to be the most popular PowerBook (and possibly Mac) ever.
