see most of the apps u r talking abt are sort of the types whcih need to idiot proof. as yet linux is not for the dumb users. and dumb ppl who tend to use linux eventualyl become smart. it may take time before linux rekons the desktop market ... but surely when u talk abt servers and killer apps ppl have resorted to linux.
one more very important idea that i support is that Just Because Linux is Good, Stable, Secure, Fast, and the Best; It doesnt mean that everyone on the planet must use it. There always should be some space for improvement ;)
take care Harsh
