I'm very satisfied with the change to debian.

After the switch to debian, I am very satisfied with the Linux Release Technology-Debian information. The following is a detailed description. I switched from opensuse to lenny. After a series of configurations, I felt very satisfied. I had completely customized the installation and there was no additional things.
Download is aria2, and the rest are on the desktop. Cairo-dock2.0.5 (with OenGL enabled)
