As the others have said, don't go to a Mac because of crashes as you'll quite likely end up disappointed. Depending on what you are doing with the computers, both can crash just as easily. Both can be just as stable too. Switching because of security issues or because you just like using the Mac better, and it can do what you need, are far better reasons to switch. Another option if you want to avoid crashes and are willing to put some time into it, is Linux.
