HotHardware.com posted a review on the Presto Instant-On Operating System

With the growing popularity of inexpensive netbooks and nettop PCs, the Linux operating system (often installed on the lowest-priced budget units) is reaching a wider audience--although nowhere close to giving Windows or the Mac OS a run for their money (albeit the Mac OS is based on Linux). Some pundits even argue that the Linux OS has finally matured enough to the point where everyday computer users can use it with little trouble. This might be arguable, but the often free or inexpensive nature of the different Linux distributions, as well as the plethora of free open-source Linux applications, makes the OS an appealing option to users on a budget.

But what if you could "dumb down" the Linux OS to its bare essentials, limit its focus to mostly Web-based tasks, make it dead-simple to use, and sell it for less than $20? Could that appeal to users? The folks over and Xandros think so with their Linux-based Presto OS.
