just for the record: last day off my vacation in mexico and i dived into the Carraibean with my digital camera into my pocket :) (don't ask why) and althogh the camera is now mearly scrap (pentax optio s) the memory card works fine and i didn't lost any of my vacation photos with would have been a lot worse - so SD cards are water proof and salt water proof :)
Positive

It's pretty nice and comes with a little book with interesting proverbs too. I'm not sure if it really helps to relieve stress but it's makes a fun distraction once in a while. The only complaint is when other people play around with it, they always spill sand out the box..
Positive

This was the first Anne Perry book I have read, but it will be the last. I found the basic premise of the main character's amnesia to be a gimmick. It irritated me that he would never "come clean" about his lack of memory, especially when we find out that the people he worked with could see through it. I have enjoyed other murder-mysteries where the villain was a lot less obvious to the reader. It seems from her sales figures that I am in the minority - what am I missing?
Negative
