You don't have a hardware to go with Fedora. You could ask Intel to do it, to have their laptops pre-installed with a working stable Fedora desktop. I know, there is no stable Fedora desktop, and you don't want to invest money in it because it's not making a profit.
About Ubuntu, it's not stable either or anything close. I would be willing to pay a fair price for a stable desktop, but it has to be popular so its future support is guaranteed, and it want be popular if its not pre-installed. As I said before, RHEL is too outdated for a desktop user.
About Linux missing the Desktop. I know, but there are more than 1000 Linux distributions and various versions within each.
