iPod Touch and MacBook Updates for September?
Analyst Mike Olson predicts that the iPod Touch will be tweaked to resemble Apple's new iPhone 3G and also raises the possibility of price drops and/or capacity increases. Recent Firmware hints have suggested the iPod Touch could see feature upgrades as well. The expectation of a new iPod Touch is also consistent with whispers we've heard.
Olson also points to slimmer MacBooks which could also have newly designed keyboards. This prediction may have been inspired by circulating rumors and photos depicting an aluminum MacBook. Apple has been rumored to be introducing "major design changes" to their notebook computers this fall.
Apple's choice of processors for a new MacBook revision will certainly be Intel's upgraded Penryn processors which were introduced alongside the Montevina platform in July. The latest Intel processors boost processor speeds up to 3.06GHz and also increase bus speeds to 1066MHz (from 800MHz). The new MacBooks will likely also benefit from upgraded integrated graphics with the GMA X4500. The GMA X4500 benchmarks significantly faster than the GMA X3100 found in current MacBooks. While there has been some talk that Apple will migrate to a 3rd party chipset, the implications of such a move remain unclear.
