it is great speedwise.
i chose vmware for it's stability and it's established reputation for virtualization in general. but i'm sure both get the job done well. especially for a 2d game engine. i'm sorry 'the' 2d game engine...lol.
i'm glad to see other mac users enjoying having access to it. i tried codeweavers, which was a nightmare, and it would have cost more in 'donations' to get it working, then just buying a known solution. i hope wine can get it working for the linux crowd. i've run a couple of distro's of that as well.
construct was the sole reason i put w7 on my machine, and i have to say it has been worth it. every time i fire up that little icon.
