I keep reading posts about using virtual machines and think it maybe a good idea to use one until I come to do it and wonder if it worth all the effort. The issues I have are as follows. 1. Firstly it seems sensible to run it off some form of Linux - which one is not important. 2. For me the only apps that would be appropriate running native in linux would be browsing, newsreader & possibly email. 3. All the other programs I use are windows based and I don't think an alteranative for such as Quicken OE Dictionary Pageplus Turbocad Word Excel and a few others. 4. As I understand it you have to reinstall Windows within the VM and then have to do all the updates, unless you can install an image. Then have to install your programs within that install. 5. You will then surely have a slowdown in running these apps. 6. Can you run several programs within a VM or is there a separate VM for each one? 7. What happens to the f/w. Do you have to install your f/w and other security apps within the VM to keep protected or does the Linux one suffice, but if so would it be aware of Win progs calling out? There are a few other issues but those will do for starters.
