Some might say, "Why upgrade at all if what you have is working?" As is, at least to some degree, I can agree with that. However, as little as one year ago I could not use my printer in Fedora and had to have a dual boot of Windows and Linux. Upgrading over the year finally brought along many new packages that now allow my all-in-one printer, copier, scanner, and fax to work 100%. SO the ultimate response is that upgrading makes more things work for me. So, while 1 kernel not functioning for me may not be a major issue, I just hope none of the later ones dysfunction as well.
