I run a Satellite 2100CDS No infrared but I did manage to get USB running and used a webcam. I'm not sure if the modem is working. Also X works fast (currently using staroffice) one down side is when I move a window mij screen start to flikker a bit.. It's just there but I don't mind. It does not iritate me. Alsi I use the PCMCIA port to connect to my home lan and on my work. Ries
