As a possible solution for you that is much less expensive then buying a new laptop: If you own a Mac and have a copy of Windows 7 or higher, you could install Windows on your Mac using Boot Camp Assistant. Boot Camp is a free program that comes with your Mac. Using Boot Camp Assistant, you can install Windows 7 on your Intel-based Mac computer in its own partition.
As another alternative you can purchase a program called Parallels which allows you to run Windows programs without having to split your drive. Again, though, you must own Windows 7 or higher. For information on Boot Camp go here: http://support.microsoft.com/kb/2647609
