I jumped a while back
I jumped ship a little while agro from Parallels - the upgrade from 2 to 3 was particularly painful for me and for a while they seemed to be rapid-firing patches out, none of which really helped. The networking was broken in one patch, and I couldn't help but feel that we (the customers) were doing the integration testing for them.
Having said that, when it worked it worked very well and if they could just sort out some of their QA issues it'd be a great product.
I switched to VMware's Fusion, which might not be quite so 'bleeding edge' with features but I don't care (I'm a software developer, not a gamer) and it's a hell of a lot more stable.
Still, I'm a bit surprised that the Reg managed to scrape 2 pages out of this - particularly, as was noted above, as you've really scraped comments from the support forum... by definition the support forum is full of unhappy bunnies so it's a bit disingenuous!
