You have also discovered there is a lot more software around for Windows against Linux, especially for our radio hobby.
Also there is the no security update problem with those using ageing copies of XP, 2000, Vista and Win 7. Like myself whom will fall into the no support trap in another 18 months or so?
You also don't like paying for a new operating system and want it for free!
Well I might of found something that is being developed as an open source operating system that appears to fit the bill called ReactOS.
ReactOS is only up to version 0.47a, so it is in it's very early stages of development and I guess full of bugs, but it does seem to work as you would expect from a Windows operating system.
I have done a bit more research around the Web and found that that only a day ago, Chris Barnatt of Explainingcomputers.com had just made a video about the product, which I have bopped the link here for you all to watch:
This seems quite an exciting development as operating systems go, and something tight fisted penny pinching Radio Hams have been looking around for a number of years. Currently, I am not minded to move to it yet until it gets passed the beta stages, but it is something I would welcome very soon.
