One of the many facets of development involves testing you applications, programs, games. Whatever grand program you have created to improve the world (at least your company’s bottom line), needs testing.
Development machines are somewhat different than what users at large may have. In a corporate environment, regular desktops will probably be locked down and many restrictions will be placed on users ability to install, download and many other things.
Having more than one desktop on hand is costly and cumbersome (space wise).
Virtual Computing to the rescue. I really like using virtual machines. My latest Virtual Machine is running Windows 7. I’m using the Sun Virtual Box. I can use all my peripherals and it’s very stable. I can test my web apps on this machine with different broswers, settings and such. This prevent my development machine from getting ‘corrupted’, so it can do what it does best.
