What kind of desktop environments or shells are there for Ubuntu users to install?

Please list a desktop environment or shell for each:

• a description on why you like or suggest it (features, performance, etc.).
• a good screenshot, preferably of it running on Ubuntu and showing off some of its features.
• the minimal requirement for it to be usable, If there's any setting to lower it's requirement (Like kde's low-fat profile); how to enable the said setting
• some instructions on how to set it up if in the repositories, please provide a software centre link

I have requirement of converting PDF pages to images. There is a background image with some text in my file, and when I save it as an image only the background image gets saved.

Is there any software available for the same so that complete page can be converted to an image?

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.

How can I record my screen on Ubuntu?

The app I'm looking for has ideally all of these features:

1. Can record in a format that can be played back easily on any platform and/or accepted by YouTube or another popular video site
2. Can record just a window (instead of the whole screen), possibly selecting it with a mouse click
3. Can start recording after a configurable delay (e.g., I launch the app and have time to do arrangements to my desktop/window before actual recording starts)

Backup is incredibly important. Obviously there's no best backup tool, but a comparison of the options would be very interesting.

• Graphical Interface? Command line?
• Incremental backups?
• Automatic backups?
• Install method: In standard repositories? PPA?
