I managed to download the update for Parallels yesterday (on a USB 3G dongle!) and it does appear to have solved the most obvious performance issues. That is to say, Windows works as expected.
I’m not sure yet if it is truly is faster than Parallels 5, as some tweets are suggesting. But today will be a good test because my development platform is going to be fairly hammered as I’ve got rather a lot of achieve today.
I’ll post anything significant if and when I can be bothered to do so 🙂
