I installed Ubuntu 11.04 on one of my systems and I am using the Unity interface. Unity is working quite well so far but I really miss panel applets for net speed, cpu temp, and system monitor.

These applets are useful for viewing quick info. Unlike 10.10, there is no other way to get this info onto the panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look.

If you know one then please list out any third party indicators with links so that they can be found.

The PPA threw a 404 for me when I tried to add it, but it turns out is was already in the repos for 12.04, so I installed that and it appears to be working just fine. –  Nick DeMayo Jul 15 '12 at 14:15

The PPA is no longer needed, the indicator comes with Ubuntu 12.04. It also does work (but you need to start it manually, such as by typing indicator-cpufreq on a terminal) –  Scott Ritchie Jul 27 '12 at 0:33
