Maybe you should buy a computer if you want to run Linux, not a game console.
So what should I buy if I both want to run Linux and want to play games?
Or maybe you should just shut the fuck up and go kill yourself for the betterment of humanity, especially the segment of humanity that reads Slashdot and has to put up with your drivel. TL;DR DIAF!
But if you're running BES (or the free Professional if you're small), everything is encrypted end to end with your own key. That's why they are so secure; 3rd parties don't have access to your data. In India & Saudi Arabia the government has put taps on the telco provided BES, but they still can't tap your private BES communications if your server is outside.
And it all passes through the single point of failure that is RIM's server farm before reaching the client, and what could be more secure than an email that is never delivered, right?
No amount of careful planning will ever replace dumb luck.
