well said darren. I think once again this is preference and if you have something that's working well for you there should be no reason to change except if you really require different features. I purchased a high-end windows 7 machine a couple of months ago and i'm absolutely delighted with it. Latency has disappeared wich was my biggest concern and for a relatively young operating system i find windows 7 to be reliable and well oiled. I don't have knowledge about other software packages but in my opinion sonar is very underrated. kind regards len viljoen
