Macworld UK is reporting that it believes remaining supplies of PowerBooks (both 12 and 17 inch) are shrinking fast, it expects unfilled orders to be met within the next three weeks.

It should be noted that just this week AppleInsider reported the likeliness of a 17-inch MacBook Pro at NAB next week.

MacWorld UK also briefly notes that iBooks remain in good supply while the 60GB iPods are in short supply, with the white model becoming difficult to get. the 30GB version of the iPod is in good supply.
