Oh, sure, I'm not saying I thought there would be no size difference; I was just bemused at the suggestion there was a performance difference. Unless "won't fit in ROM any more" is considered a performance problem ;-) -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours. We can't possibly take such a retrograde step."
