The CloudBook is a discontinued x86 subnotebook, or ultra-mobile PC developed by Everex using a VIA processor, chipset, and NanoBook reference design.

Sales of the gPC TC2502 Everex desktop[1] left the company with inquiries from customers seeking similar additional Open Source, but mobile platforms.

The delay was needed because Everex wanted to rewrite gOS v2 for the CloudBook so it would use GNOME's window manager instead of Enlightenment 17, making it even more compatible with Ubuntu.

It was aiming to use a Linux platform for delivering a full windows experience (desktop as a service) with an app store for renting software.

The next generation of CloudBook, was advertised to have a processor running at 1.6 GHz, a 80 GB disk drive, touch pad and WiMAX.
