I'm not counting out VMWare entirely. Obviously it will depend on how soon they can catch up and the relative quality of the solutions, but there is some serious first-mover advantage here. There is also some speculation on the forums that Parallels is rushing this out in order to sell product before Apple steals their thunder with virtualization support in Leopard (but I think that a bit unlikely). In any case, it looks like one more roadblock for switchers has just been knocked down."
