Few weeks back a friend of mine was amazed (Non-IT) that you could run "two computers in one", at least that is how he called it. What he saw was Virtualization Technology in my laptop being able to run both Windows and Linux concurrently. He was looking for a cheaper alternative to run an almost virus-free operating system and somehow came to know about Linux (maybe through the recent Dell Linux Laptops). Yes, he is also aware of the "Get a Mac" TV Ads, but budget constraints prevents him from getting one.
So anyway, he was looking at my VMWare workstation and was asking if there is a free alternative to VMWare workstation where he can install Linux and enjoy the "almost virus free browsing for a while". I gave him two options.
(1) VMWare Free Player - and use the Browser Appliance
(2) VirtualBox - A nice free virtualization product.
VMWare Free Player I think is great if you just want to use their version of the operating system and your usage is limited to just browsing using firefox. If you are looking for a full fleged free virtualization product that allows you to install Linux using DVD/CD then VirutalBox is definitely worth a try.
