The other one I want is an early HP OmniBook 300. The early ones were fun, they had a 'pop-out mouse-on-a-stick' (the mouse was permanently attached via a moveable rod, it would slide into a small space on the side,) as well as having Windows 3.1 in ROM for instant-boot. Later models moved to having two PCMCIA type III slots, one for a 1.8" hard drive, one for expansion. (The expansion could also operate as two type II slots, as was standard at the time.)

What's amazing to me is that the MacBook Air is only 0.1 pounds heavier than the OmniBook...
