I bought Myst for my iPhone last week and i have to say, it was pretty fun to play it again. I actually had a better experience with it than i had back in the day when i played it on a Philips CD-i. The game is way easier than i remembered, though.
So, if you have an iPhone, buy that one and you can start play it within a few minutes. For a PC solution i can't help you, sorry.
