Here’s Onkyo’s “NES-1A music terminal,” which features a 40GB hard drive, Memory Stick slot, and CD drive. I couldn’t really find a difference between this and Sony’s Net Juke NAS-A10 as far as capabilities are concerned, but I will say that the Onkyo has a cooler color. Something like this would be a nice go-between for your CD collection and PSP (as this unit can transfer tracks directly to Memory Sticks), but that’s assuming you don’t mind your junk being in ATRAC3.
