gOS Rocket is based on the Ubuntu 7.10 distribution. It uses the Enlightenment 17 window manager instead of the usual GNOME or KDE desktops, allowing for lower memory and speed requirements. Therefore Rocket starts to work reasonably well on systems as low end as a 1GHz Pentium III with 256MB RAM. Because it leans heavy on on-line applications built on Web 2.0 and AJAX technology it also does not use much hard disk space for applications, the whole system fits comfortably in less than 2 GB. Also many of the documents created with Rocket, such as Google Docs documents, can be saved on Google servers instead of on the local hard disk, so Rocket can work with very small hard disks. In this respect a gOS Rocket PC has many similarities with a Thin client, but gOS Rocket also integrated Google Gears, which suggests that in the future the on-line google applications can be used while off-line.

gOS Rocket's primary features include a Mac OS X Leopard-like Dock called the iBar, featuring icons for the following applications: Firefox web browser, Google Mail, Google News, Google Calendar, Google Maps, Google Docs and Spreadsheets, Google Product Search, the Blogger YouTube and Facebook online communities as well as Meebo to online chat with Yahoo! Messenger and Windows Live Messenger users, Rhythmbox (ITunes like program for music and radio), Skype, Wikipedia, and the Xine media player. The rightmost icon is for Faqly, a system developed for Rocket to offer a built-in online community based help system. Other programs can be added to the iBar as well.

gOS Rocket also supports mini applications that run on the desktop, such as the clock.

Also available are a number of card, board and puzzle games, the photo and picture editing program the Gimp and the OpenOffice.org office suite. Other programs can be installed using the built-in Synaptic Package Manager.

Google desktop search is integrated at the center of the desktop.

gOS Rocket is still in the beta stage and is continually producing updates that end users can automatically download through an included auto update manager.
