Helium for diving is going to be a different mix than what's used for balloons. In diving it's used to reduce the partial pressure of oxygen, and also to quickly diffuse back out of tissues when returning to the surface. Very different application!
Sorry i was referencing "Balloon grade H is the least pure at 97.5 percent." from the diving article
Some of this is not _just_ a corporate problem. Why would Winzip have an auto run application and tray application in the first place? Every single app seems to think they need one, and it's a classical tragedy of the commons. Perhaps on a virgin Windows install, your app with autorun and a tray icon will be more responsive. But when 20 other apps pull that same trick, no one wins.
This is actually one of the reasons I'm not excited at the idea of Linux defeating Windows. If it did, corporations would just start crapping up Linux the way they've crapped up Windows.
