I have been using Linux since 2001. And amongst all the Linux distributions and other Operating Systems used Debian is my favorite.
I love debian because of the bunch of reasons:
- Its free.
- It is the best development environment.
- It is not bloatware like other distributions. It works on my old system too.
- The /usr/share/doc directory is great.
- People think debian is “only for geeks” distro. No its not. It includes all the applications that can be used on daily basis like Office suites (Openoffice, KOffice), Audio/Video players (Vlc, Kaffiene etc), Browsers (Firefox is known as Iceweasel in debian), Messengers (Pidgin, Kopete) and many many more. My sister is not a programmer but she uses debian too.
