I have two laptops running giga - a dell 5160 p4 2.8ghz with 1.5gig of ram running GS3 and an older dell 250 2.4ghz P4 with 1 gig running GS2.5.

Its difficult finding laptops that have firewire and can take more than agig of ram. I would love to hear any other working solutions from fellow portable musicians
