Changing my default distribution...

Recently I tried to install ArchLinux. I've succeed and really got into it. It is minimalistic, rolling-release distribution, which is the right one for me :D
After a day or two of general tweaking my distribution was ready to use. Quickly it became my primary distribution.
My recommendations: if you like to use really customized system and if you like newest versions of software, don't hesitate to try ArchLinux.

For first-time installation I recommend The Beginners Guide. HF :)
