PCs for the Poor

News.com discusses the various designs and mentions the thin client:

What it is: Thin clients are inexpensive, lightweight terminals that rely on servers to store data and crunch numbers. They’re used by banks, airlines and insurance companies in the west, and entrepreneurs such as India’s Rajesh Jain and academics like Deepak Phatak and Ashok Jhunjhunwala are promoting them for rural use.

Pros: Because they don’t need fast processors or a hard drive, thin clients can be produced for about $100, including a used monitor. Some designs use an existing TV to cut costs further. The fact that the software is centralized on a server also makes it easier to handle upgrades and control viruses. Interestingly, local leaders, rather than multinationals, are behind this one.

Cons: Thin clients rely on servers, so if the server goes out, the terminals go down. Users have also said that thin clients can run slowly if too many people log on to the server, but proponents say the technology has steadily improved.
