> I once had a PDP11/05 CPU box (the 5.25"
version) on my lap while I was
troubleshooting some part of the hardware (I forget
what). On the
grounds that the end of this troubleshooting it was running programs
and is clearly a computer, does that make the 11/05 the 'first laptop'?
The absurdity of that mental image proves my point: a laptop runs on its
own power, ergo the Compass isn't one. It's small, flat, clamshell, and
"portable" by design, but not a laptop.
