The original “Toilet Seat” iBook from 1999is the only one I can recall that came with a handle: https://lunduke.substack.com/p/ode-to-the-clamshell-ibook-g3...

Also the eMate 300! https://en.wikipedia.org/wiki/EMate_300 (from 1997)

(And if you go much farther back, the TRS-80 Model 4p - but "sewing machine class" portables kind of had to.)
