Apple's new Macintosh PowerBook 150 notebook computer is faster and lighter than the 145B model it replaces at the low end, but does not have enough ports to function as a user's only system and is a relatively poor value at $1,449. It uses the same case as the 100-series models, a 33-MHz 68030 CPU with no floating Point Unit (FPU). The PowerBook 150 also includes 4MB of Duo-style RAM that can be expanded to 40MB. The 150 weighs only 5.5 pounds and is the lightest non-Duo Mac to date. Features include a lightweight SuperDrive floppy drive, a backlit passive-matrix screen and an IDE hard drive. There are no Ethernet, video-out or Apple Desktop Bus (ADB) ports. Apple claims that all 100-series accessories will work with the 150, but there are lingering problems with third-party modems. ClarisWorks is bundled with the 150 and makes creating a wide variety of documents easy. Apple has left out the system disks to save costs, supplying only a single emergency start-up disk with a utility for backing up the hard drive onto nine floppies. The use of IDE technology both saves cost and improves performance, but IDE is incompatible with most Mac formatting utilities, which are designed for SCSI drives.
