I'm going to agree with people skeptical of single-cores. Really, the pinnacle of single cores was pretty unanimously the P4. It's only so-so by today's standards. Nearly NOTHING gets shipped with single cores anymore except mini-laptops. Until they shrink a dual-core to the point where they can fit it in one of these, I don't think any of the minis are really worth much. It might be a good thing to have if you really need it and you don't want to pay massive amounts of money. But as soon as the hard-drive gets bogged down, and it gets more than 6 months old, it might start huffing and puffing to do the same workloads.
