Right now, my biggest nightmare are VST plugins. They are in fact the reason why I didn't upgrade my PC from an i7 920 for years. I estimate it will take me at least a week of full spare time use to deinstall them on the old machine and re-install them on the new machine. Steam would make many people a huge favor if they managed to enter the pro audio market, which still comes with their own installers, licensing schemes, DRM, spurious hidden support services, etc. All the bad stuff, exclusively for honest customers.
