Linux sucks to learn but it also provides many benefits once you learn it, and there are many ppl willing to help you out in the linux, ubuntu, etc... forums.
MY last laptop had a cpu problem somthing about the core clock or something like that, i didn't know i had that problem on windows, once i changed to ubuntu it was evident that i had the problem. Every 1 minute the computer froze for 4 seconds, if i was writing the letter r for example it would write "rrrrrrrrrrr", i posted about that problem on the ubuntu forum and a guy sent me a tutorial of what to do, he explained it very well, my computer became much better after that.
So, if you are having problems with ubuntu, linux, the language in both of these is the same i think, just post on the forums, they are a cool helpfull community that would help you easily if you need!
I don't become a witness because i don't have the network or the money to become one.
