As to the question about the $100 tutorial, though, that's... well, a lot, but I suppose it depends on whether "Vim Valley" takes an approach that "clicks" for you in ways other things don't. Practical Vim is $23 for a DRM-free ebook, and it has a lot of hands-on exercises; I learn pretty well that way, I've found.
There's a ton of free info on Vim around and it's perfectly viable to learn it on your own that way, it will just take a lot longer. Obviously I'm biased, since I made Vim Valley to be exactly what I think is the fastest and most enjoyable way to learn Vim.
If you choose to disbelieve me, that is your choice.
If you email me the details of the bug(s) you're running into to hello@vimvalley.com I can try to get them fixed. Otherwise if you're not averse to Chrome everything should work fine with Chrome on Linux.
