to use it. It WILL require a level of dedication from you.
If you don't want to use it, or you don't want to put the effort into learning it, that's fine - don't use it.
As for which distro - pick one. I don't care, and am not going to get pulled into a debate on which distro is better. However, most of the people on here know debian and will help you with debian problems because that's what they know. (Asking Redhat questions to Debian users isn't going to elicit a multitude of responses).
But the first question must be a desire to learn. There is NOTHING wrong with not wanting to learn Linux. If Windows works for you, why switch?
