by Adam Pash When I made the switch to Ubuntu Linux on my desktop computer (that is, if you can call triple-booting Windows XP, Vista, and Ubuntu a "switch"), I was a little worried about finding the applications and tools that would make me as productive working in Ubuntu as I am working on Windows. After a little searching around the interweb, however, I've been more than impressed with the number of great, full-featured applications available for Linux, many of which outshine their Windows counterparts.
VMware Player allows you to run entire operating systems in a virtual machine , which runs on top of Ubuntu or Windows. To the guest operating system (the one running inside the virtual machine), it appears as though it were running on its own PC.
