Linux maybe. Mac? Mac is more intuitive to use than windows. I am currently using a Mac, and its interface is way simpler and more intuitive than windows. Plus, it doesn't give you useless error messages that you can't do anything about. It takes getting used to, especially if you have used only windows in the past, but in a couple of days, you are all set. You never have to use the command line (unless you want to that is). Most things work straight out of the box...
Linux, yes, but the user interfaces these days, especially KDE are much like windows. In fact, I dont see a lot of difference. Again, rarely do you need to use command line unless you want to use some esoteric software that the package managers do not have.
That said, you are right - linux adoption in India is tricky. Why?
1) Unfamiliarity - the small system integrator you buy your PC from will not know anything about linux (installing it is also easy these days, just like windows). 2) Pirated software: Indians dont pay for software. Even the windws we run is pirated, so where's the advantage in using linux? People want adobe photoshop or CS3 installed on their machines (pirated copies, of course) so linux is pretty out of the question...
One thing though... windows' newest bloatware, Vista has had people complaining about the amount of resources it consumes even when idle. If XP becomes unavailable in future (dunno) could that cause a shift esp ppl who dont want to upgrade just for fancy gimmicks?
