Yes... Playing devil's advocate, suppose someone asked you:
"I'm thinking of installing software on my wireless device. The application will have access to the books I bought, to my private PDF documents and to the passwords saved in the browser. It's developed by a team of hackers in China. Do you think it's a good idea?"
It might be totally safe.
Or it might be something that you read in the newspaper someday: "Thousands of ebooks and user accounts stolen through Kindle hack." Then people comment on it and say "They gave access to their device to a team of Chinese hackers... What were they thinking?"
My feeling is that there's a 90% chance that it's safe and respectful of privacy. But I don't know if I want to take chances with the other 10%... LOL...
