Last night, I watched Casino Royale, the latest movie of the James Bond franchise. It's easily the best of the series, and I was thoroughly impressed by Daniel Craig's performance. But as the writer for The Smart PDA, I also discovered why the bad guys should be more careful when using their smartphones.

Sony-Ericsson played a big role; their K800i and M600i models were prominent plot devices. To avoid giving away the story, I'll just say that many times in the movie, 007 tracked down the villains through their smartphones. And upon finding them, expertly foiled their plans and used his license to kill.

So if you have plans of conquering the world, or at least make money off the suffering of others, use your mobile wisely. Never use it in public view, and keep your personal data secure. Smartphones may be harder to track than landlines, but thanks to agents like James Bond, they can lead to your doom. :P
