My PC has been on its last legs for years. However, I do run two flat 21" CRTs off it, which is very nice. I'm still trying to decide whether to order a G5 in a few days or get a powerbook. The portability would be really handy, and of course when I get home I could just plug it in to one of the external displays. One advantage that the G5 would have is that I can easily use both monitors (I'd have to get a vga-adc or a sun-adc adapter for the second one, the first could use the included vga-dvi adapter). However, the powerbooks only have the one MiniDVI or DVI port. Is there any way to add a secondary external display? Any expansion card? I could use s-video, I suppose, but the quality would not be the best. Can anyone tell me what the s-video is like in the powerbooks? Thanks!
