@cbae: I have complained voiceferously for the last 4 or so months with not as much as an answer from Microsoft, and I now need to suggest what they can do to make me stay, on top of several thousand pounds that I have paid in licenses to them this year gone?

I think you are forgetting who it is that pays Microsoft wages, and British companies like a lot of others pay 2 to 3 times as much as you do, times are hard and money is hard to come by, as someone that has developed exclusively for windows for the last decade, if they cannot see the reasons for exodus, then they are a greater company than I. Please be sure to check how long I have hung around in these forums.
