PowerBook Duo 250

Compared with the PowerBook Duo 230, this model replaced the passive-matrix screen with a 9.1-inch active-matrix grayscale panel, which is much sharper and faster. It kept the 33 MHz 68030 processor and came with a 200 MB hard disk. A Type II NiMH battery gave 25% more capacity. The case and dock connector did not change.
