I had an old laptop with not enough ram or a large enough hard drive to upgrade from Windows 98. It still ran fine so rather than ditch it I decided to reformat and install Ubuntu. I'm using it to type this post. I had a Windows XP computer and doing anything with this one would present no loss. I had very few problems and what I had was simply a learning curve. Many things about using Ubuntu were intuitive but several things took some learning. Anything new will involve a learning curve but nothing has been impossible. I actually enjoy learning new things. This system is fast and everything works well. It cost me nothing but a little time to make a nearly obsolete laptop a well functioning machine again. Having my Windows computer "just in case" was a nice security blanket but now it is no longer necessary. I really like this version of Linux and would have no qualms about upgrading my Windows computer when it becomes obsolete. If you are willing to learn a few new tricks without parting with your hard earned money in the process-go for it!
