Books here in my country costs too much especially the newer ones

. So i resorted on ebooks.
I bought a reader ultimately to stop my eyes from straining any further. I am now wearing glasses (tried contacts but it causes more problems for me) and i have no intentions of letting my eye grade go higher than what i have now which is ridiculously high for my age. I've been reading ebooks with my nintendo ds lite and my psp for at least half a year now so yes, i admit that i have been abusing my eyes.
