So they can easily switch between operating systems without restarting.
Also if an OS crashes in VMware only VMware crashes so it is quicker to get back to where you were.
Running an emulated computer that in turn is running an OS also aliviates the chance of a hardware failure from incorrect coding, and makes testing the software on different computers/configurations easier.
Its mainly a tool to make writing programs easier and quicker.

Hi,
Agreed that VMWare is a resource hog however it provides enormous cost savings, especially for creating testing sand bags which are of no use later if we invest on real hardware for this purpose. It also provides you with the independence of working on multiple operating systems without restarting your computer every time.

I use it on my home PC’s
My server for example can run 3 virtual servers at home – now what is the power consumption of 1 computer versus 3?
I have also seen some companies running as many as 20 virtual servers on one piece of server hardware – what is the power consumption compared to 20 servers.
It’s all about need and cost – they do things like this to keep cost down – and yes they do figure in power ocnsumption into the cost.
Why do you call it a “hog”? Considering what VMWare is doing, I think it does it pretty efficiently. You’ve got an entire OS running inside of VMWare, which is taking care of bridging virtual devices to real devices, translating/bridging network connections, among other things.
If it’s bogging down your computer, it’s time for a new computer. I’ve run windows under linux on vmware for many years, and even years ago it worked great. On current hardware, it is incredible.
Not to mention, VMWare’s latest announced product is a hardware hypervisor, so there really won’t be much of a concern with resources, since there won’t be a host OS!
