I suppose they've made/ upgraded the 2.x versions keeping in mind the developers as things do not work at all without applying tweaks. I would say 2.x versions of this extensions are not meant for those without coding knowledge. Still a great extension but only for those who can apply Hacks and Tweaks
GO FOR THIS EXT. IF U HAVE GOOD KNOWLEDGE OF CODE - Does'nt work out of the box
Thank you for your comments, however I would like to suggest that VirtueMart is perfect for people who just want to install a shop and get it working, based on their own limited development ability, and likewise it is perfect for developers who want to take a free product, power bulge it for their clients, and provide a world class product that works.
As with any product, when you start hacking and tweaking, there are other implications to consider, this is where sometimes issues arise.
