Welcome to Linux. This is only like my second post on these particular forums, but I've been using Linux since 2008, and it's been nothing but great.
I will say, though, there is some learning that you have to be willing to do. Personally, I found the learning fun, and enlightnening, and I've learned more now about how computers actually work in the last two and a half years than I have over the entire span of using them everyday.
There are some things I will say, though. I, personally, have never dual booted with Windows. I've dual booted with many other things, but not with Windows. I've never had Windows as something I could fall back on if something went horribly wrong, and I am the type of person who enjoyed the learning and discovery of figuring out how to get things to work, rather than just have them work for me (possibly in a manner I don't prefer, which is why I left Windows). But that's just me, and I understand that not everyone is doing things for the same reasons I do things.
What I'm getting at here is the same thing that someone told me when I was deciding to make the switch. Linux is Not Windows
. I wasn't given this to read in a condescending or discouraging manner, and those aren't my intentions here. But it's something that should be understood (it also avoids the comments like "why can't this just be like Windows" or "why do I have to be almost a computer programmer to get this to work").
It's really not that bad. Linux is the most enjoyable system I've ever used. It's great, but just be prepared to learn a lot, but enjoy yourself, and have fun.
Once again, welcome.
