Apple Insider suggests Apple may be planning to release an ultra-portable notebook:
The Cupertino-based firm's return to the sub-notebook market, as AppleInsider billed it in an exclusive report this past February, had the Mac maker scurrying to complete its initial design around mid-year.
Evidence suggested the Apple World Wide Developers Conference, which invades San Francisco in June, could have served as an ideal venue for company chief executive Steve Jobs to first flaunt the device. That's now unlikely to be the case.
Citing a maturing timeline, people familiar with the initiative now have the chic notebook tracking for the latter half of the year, with a contingency plan in place to transition the device into a Macworld 2008 product should engineers require the additional time.
