Searching For Development Environment & IDE's

I was searching today if there are any other tool that I can use other than Eclipse for developing Android apps. There are some that looks promising that I will try on the way and compare with each other. Some of those that I have found are; NetBeans, Processing for Android, Intellij. Apparently you can use Visual Studio (Yeah you read it right) for development and debugging but I am not going to try it. At some point I will share how you can develop an application using a normal text editor like vim (or notepad if you will) after I figure out the way how Android SDK works.

Important note: I will use Eclipse as my primary development IDE but I will also try to develop with other tools and compare with them.

Note: If you have any suggestions about using the IDE's above or any other please comment. You might save me from a lot of work

What I am going to do?

I will go step by step from the documentation of the Android SDK to installing the development environment. Although I am very optimistic with the results lets see what future is holding for me.

Important note: My development environment is going to be Ubuntu 10.04, but because of my laptop I might change to MAC OS X from time to time but that should not be an issue since I will share how to do things in both of the platforms. I will not be using any version of Microsoft Windows at any given time.
