Actually, that's kind of why I like it, think of it as the Volkswagon of PowerBooks and the PB Gray bridge between the PB100 the PB190 and the rest of the IDE PBs.. The Duo's were the Thoroughbred heir's apparent to the 100, the 150 was the gelding bastard by a 1x0 series Plow Horse.
I think of the PB150 as a Brilliant PB100 on steroids and speed.
If I ever get that dratted memory adapter its RAM will increase by an order of 32bit addressed magnitude, 4.25x the 100''s and more than 2x any other 1x0 PB. Sure it's bigger, but it has a full 640x480x4bit LCD and they threw the FDD back into the larger case in order to house it. The 150 came off the lines ready for a silent HDD replacement and only key feature left out of the 100 spec was the ADB port to power an external expansion device on the road . . .
. . . and that gives me another pair of hacking opportunities! [}
