So, I created this thread to know what OS(es) do y'all guys uses. If possible, reply your opinions about them, and why do you use it. Answer to my own question I personally use Ubuntu and Windows (dual-boot), because I feel like both Linux and Windows has it's particular things. For example, Ubuntu is excellent for developing things in languages like C, C++ and Java and also it's stable enough for daily usage (browse internet, skype, etc). About Windows, I prefer it for gaming, since it has a sea of games, applications, etc., and .NET development. .NET is excellent for developing massive GUI projects, due to Visual Studio's robust designer. I like it, and I personally did a lot of things in it (however none of these I did finished).
