RE: Sim recommendation for a laptop
I'm running G2 on an IBM R51 (1.6GHZ, 512mb RAM, 32MB ati radeon Mobile) and a Toshiba Satellite 1.6ghz 256MB, both run fine.
Can't tell you about G3 because I don't have it, and based on my experience getting support and updates for G2 after paying over $300 for it and the add ons, I will not ever buy anything from knife edge again.
