I actually bought a couple of books at Chapters last week. Yeah...not crazy about the high prices. And, as mentioned, amazon free shipping is only $25.00 so it's usually easy to fill an order to that amount (most of my amazon purchases are Blu-ray Discs).
Fact of the matter is that I really dislike e-readers.
I've had a Sony e-reader for a year and a half. Honestly, the thing I find it most handy for is saving PDFs of operating manuals. I can keep instructions books for my various cameras and such handy without hauling paper around. And I use it to check out classic, public domain literature.
But I really dislike it for reading books in general. I dislike the feel, the look...pretty much everything. For me, it's a utilitarian device; a tool. I use if I must.
My computer is in my personal library. It has books I've owned since I was kid. I've even got some books my late father owned in the 1950's. I get great pleasure from thumbing through them at random and discovering new things EVERY single time I do that.
In 18 months of owning an e-reader, I've never had the pleasure of thumbing through it and suddenly discovering something I hadn't see before.
