Amazon's Scientific E-textbooks Suck
I had high hopes for the e-textbook. I imagined live equations, live links that led to interest external sites, and other interactive features. Having bought a few Cambridge UP and other scientific e-books from Amazon, I have to say that they all suck. The equations are typically reduced to tiny images that don't magnify with the text. Amazon's proprietary text crapware apparently can't render them in magnifiable form. Needless to say, the other desirable features are also missing.
I guess real e-textbooks will have to wait for another generation or so.
