i've got openbsd 3.0 running on my primary laptop, a dell latitude cs. this is a pretty good laptop ... very light, long battery life (4+ hours), decent keyboard. the only problem is that there are NO serial ports (no infrared, but I don't care so much about that). if you feel that you'll be needing a serial port, buy the port replicator when you buy the machine, it's much cheaper that way. everything is working including the sound card (from 2.7 onwards) ... it's an integrated chipset into the NeoMagic 256AV.

I was very excited to see support in OpenBSD 2.9 for the builtin SCSI chipset (pcscp) from the docking station. Once I find a terminator for my old CD-R I will try it out.
