I managed to squeeze the following into only 601 grams, or for those more comfortable with non-metrics weights, about 1-1/3 pounds:

• 18 issues (combined) of Asimov’s, Analog, and F&SF.
• 4 issues of Clarkesworld
• 4 issues of Lightspeed
• 129 books
• Seasons 1 & 2 (26 episodes) of Doctor Who
• Season 4 (21 episodes) of Star Trek:Enterprise
• 2 movies (White Christmas and Love Actually)
• All of my works-in-progress and related notes
• 27 issues of New Scientist
• Enough kids shows and movies to keep the Little Man occupied

And you know what? There’s still room to cram more into that 601 grams.

Maybe there’s something to this e-format business after all.
