I'd go with the Toshiba. I remember back in primary school, all our teachers had Toshiba Satellites, the old gray ones. They were awesome.

As for the ethernet jack, a lot of low end PCs are like that. A while back I refurbed a Toshiba Satellite Celery-M 1.5 (i think it was, anyway) for a customer and it had the same thing. I removed the cap and plugged it into my network, just to see what would happen, and nothing happened. A look at the guts of it later on revealed that there was no ethernet circuitry on the machine whatsoever.
