Can any of the S456 tell me what the line in capabilities are? Can I use this to bring in audio from an external source to record (say a small mixer or little recorder box?)

I've narrowed my choice down to the S456 or the Sony A150. Just want to make sure what I *think* the Toshiba does that is better before I spend the little extra for it. I've had 3 vaios, and they aren't bad, but I'm considering jumping to Toshiba - seems like more processor, etc for the money.

Thanks,
