Until a few months ago, I stuck to books as well. The drawback was that there were a bunch of old, fairly high-profile books that I wanted, but they were never stocked by local libraries and local book stores (Coles, McNalley-Robinson, Chapters, Indigo) and I could never find them at used books stores or used book sales events. Online book stores had a few of these, but the prices were wild and had shipping charges tacked on top. Also, I like to keep my books, and storage has been getting difficult.
So, I finally decided to buy an e-book. I bought a Kobo with Wi-Fi (but not with touch-screen. I'm familiar with touch-screen UI's, I know it's popular, and I don't particularly care for it on handheld devices for several reasons). I've since been able to find and buy the books I was after on-line, and I've solved my book storage problem. And, wow! The on-line selection is vastly better than book shop and used book store selections. I've even been able to buy and capture books from authors who had been screwed over buy publishers and had never had their excellent works available through traditional channels.
The Kobo is a minimalist e-book. It only works with ePub, PDF and (I think) txt. It doesn't have a qwerty keypad, just a few buttons and a directional cursor keypad. For me, it's perfect! It came pre-loaded with 100 books (from Guttenberg project and from a pool of free books as well) which also attracted me.
I have been using Calibre to convert other formats to ePub, usually from PDF, and to add my own book cover graphics to e-book files.
I'm been removing DRM from purchased e-book files as well, so that I can archive them properly for future reference, and so that I can buy a book for someone else and transfer it to them (Geez! Everything that DRM touches just reeks of uselessness, doesn't it?! My country hasn't passed an American-style DMCA bill yet... fingers crossed). The tools to do so are pretty easy to find.
