We already looked at the Intel solution to the low-cost school computer. While they used the laptop form factor, AMD is using the Mac Mini form factor. I like the mini form factor better because under harsh environmental conditions keyboards and power supplies are likely to die often. Replacement an attached device is much easier than it would be for a device built into a laptop.
Another important difference between the two computers is that AMD's computer is sold or leased through the ISP. I gather that one cannot buy this unit.
