To be honest, I have bought maybe four books in the last several years, and regretted all of them. The biggest problem with dead-tree books (besides questions of quality and accuracy) is that by the time they are published they are at least six months out-of-date. I bought a cheap monochrome laser printer, run it in toner-saver mode (if I were running it on Windows with the Windows drivers I’d even have the ability to print on both sides of the page in even/odd mode), and find more current, interesting, useful articles and tutorials than I have time to go though, on any subject I happen to be working with at the moment.
Borders will be closing their doors shortly, anyway.
One of my main sites for all things development and design related is
A List Apart.
