Apple's theory has always been that if they control the hardware, they don't have to compromise their software. That results in really remarkable things.
Other contractors I know in the west coast just leave their cell phone in their car when they go on base. It just sounds like your friends are using the old "I have a security clearance" excuse to not have a cell phone, which, if its the case, more power to them. :)
A replaceable battery? A slide out keyboard? A normal headphone jack?
No, you're right. Choice is REALLY BAD. Let's all buy Apple stuff and be happy that the Gods have even thought of us.
Are you talking about the recessed one in the first generation iPhones? Because at least the iPhones had a standard 3.5mm headphone jack to begin with (albeit one that wouldn't work with some third party headphones because of their size), unlike the tmobile G1 (you know, android and all) that has no standard headphone jack at all.
