As all of you might be knowing that distro is a short name for Linux Distributions, here I list many distros which have gained a lot ground of late and can be truly called desktop OS. Some information are also appended along with them so that you can make a nice decision. All comments,suggestion and feedback are welcome.
Ubuntu: This is the best and the most usable Linux distro when it comes to general use. A Linux distribution should not just work properly, it should have a strong community, nice documentation, large number of HOWTOs and TIPS/TRICKS. This is the place where ubuntu beats all distros hands down. If you have problems downloading from the site or have slow connection, you can order its CD for free! Order Now
UbuntuForums: This is one of the most busiest forums and too exhaustive for any one to follow. In light mood its so vast that one needs to be unemployed to keep track of all the threads 😀 Its claims over 6,00,000 users on the community. Even if you post a n00b question, you should expect to get multiple instant replies. One thing special is the patience in community members. The same n00b question is asked again and again by different members and all of them are answered by the people in polite tone. Its a non-geek hangout
Ubuntu Wiki: This is one of the best documentation I have ever seen, one stop destination for all problems and tweaks. The wiki consists of two parts official and community. Official one is a bid narrow thing and to the point explanation whereas community section is highly exhaustive.
