I purchased this to use with a Novatel MiFi. After plugging in the MiFi and turning it on, the charger produces a high-pitched pulsating whine and then powers itself off. I tried it with a Kindle 2 and got the same result. Buyers, check the current draw of your devices against the maximum current output of this charger before purchasing.
Other than the high-current problem, it seems to work fine. I don't have any low-current USB devices to charge, so I can't say for certain.

I've been using this lens for a few months without any major complaints. It can evidence vignetting at 10mm, which becomes more pronounced when you add a 77mm polarizing filter. The physical motion is superb and it's a solid lens. It's missing obvious hyperfocal markings, but you can use the focal length and distance marks to get accurate hyperfocus anyways. I hope this helps others who use this lens.
Hyperfocal lens settings (partial list):
10mm: f/5 @ 1m
10mm: f/11 @ 1.5ft
12mm: f/8 @ 3ft
12mm: f/16 @ 1.5ft
14mm: f/10 @ 1m
14mm: f/25 @ 0.4m
17mm: f/16 @ 3ft
20mm: f/22 @ 3ft

This book was very useful in introducing me to the mechanics of quantum computing. Using simplified concepts and compartmentalized explanations, the book manages to explain the core concepts of quantum parallelized computing using tinkertoys, gears, and black-box algorithms. I've had some previous introduction to quantum theory, but the limited depth provided by this book is exactly what I needed to base further exploratory reading on. It's a perfect "first" stepping stone for anyone interesting in exploring the field, either at depth or at leisure.
