Ian - that is another question, not an answer .... :-) To answer your question: My Al-book has 1Gb RAM at the moment, and I can increase it to 2 Gb max. My VM is currently running at 8.32 Gb. So there is no way I can ever put (let alone afford) enough RAM to eliminate VM. My idea was that maybe the VM can be moved to a 4Gb flash drive to speed things up. What I am not sure about is how the OS would handle more VM (eg the current 8+ Gb) than the (4Gb) drive has capacity for... Just exploring what is possible, what the limit is. Trevor
