That's a really heated and debated area. I haven't seen any medical studies that show it's a LCD problem, I think it's more a problem of ergonomics, but some people report e-ink is better for everything, for them LCD is terrible, bad for the eyes etc...

E-ink has better battery life and can be read outside in the sun, that cannot be doubted.

I believe you cannot buy from the B&N store outside the USA, even on the computer, unless you use a VPN to make them think you have a US IP. You can buy from Kobo and other e-books stores that will sell outside the US and upload them to your Nook/Nook Color though.
