I don't see your point. Skype was done in Delphi, and it was pretty much end-user and very successful. There are many other apps: Skype, Nero Burning Rom, WinRAR, Partition Magic, Panda Titanium Antivirus, TuneUp Utilities, Aida64, BeyondCompare, Total Commander, CloneDVD, Ultra ISO, KMplayer, Gold Wave, Sound editor. And I am sure there are many others.
