No. Would a 68k based laptop be possible?
Considering they exist I'd have to say yes

Regarding the poll however I didn't answer as there was no option that matched my thoughts.
Yes, I'd buy an OS4.x laptop, and I'd even pay a bit more for it vs. other hardware, but I still have my limits. Unfortunately this premium is unlikely to get to a level I'm willing to pay. Give me x1000 or x5000 or thereabouts spec for $1k, or sam460-ish level for up to about $700 and I'd probably bite. $700 to $1000 I think is still pretty expensive for netbook type specs, but given the niche I'd still pay it.
