> What phone manufacturer are you worried about going out of business?
Every single one of them could go out of business in the future.
It happens all the time to companies you'd think were "too big to fail":
MCI
Sears
Montgomery Wards
Mervyn's
Gemco
Best
Pioneer Chicken
Radio Shack
Sierra Online
Pan Am
Atari
Commodore
I haven't even mentioned the number of car companies that have bit the dust, that people never thought they'd go away.
All of these can go away - and likely will go away.
It's quite possible that Google, Facebook, Amazon, and many others might go away.
I'm honestly surprised that IBM is still around. Sun Microsystems is gone (more or less - they are part of Oracle now, mainly as a name - you might know about the language they developed called "Java"); so is Silicon Graphics...
Apple of course still exists - but it wasn't that long ago that Microsoft had to pump some cash into them just to keep them going so that they wouldn't be accused of being a monopoly (or something of that nature). It's kinda funny, given where Apple is today - and where Microsoft is as well...
Yeah - any and all of these companies can go away - and in fact are likely to.
