Do most global and big companies (fortune 500) now use OSX (apple) instead of Microsoft?

I just noticed that most companies and people on wall street are using macbooks and imac(s) in their work place instead of microsoft running laptops and computers, in addition many use the iphone instead of android phones. Does this mean that apple is much more easy to use, more reliable? More stable? I mean ofcourse, considering the costs, I don't think they would invest in such machines right? So there must be really something about them.

Not even close. The last time I looked at the numbers, MS was still around 93% of the market share. Apple is still a niche product, and won't ever come close to taking over MS.

  • Why do most celebrities and Hollywood stars use Iphone instead of Android phones? I know some celebrities who endorse Samsung and other smartphone brands but behind the camera, they use Iphone. I know some people who are not wealthy; not even come from affluent clan, people don't earn that much but they managed to get an iphone through postpaid plan/instalment basis. They don't care if they will bury themselves into debts just to make themselves look wealthy/classy.
  • My Blackberry broke, and I have a jailbroken iPhone 4. Can I use that instead now? My Blackberry broke and I'm worried whether that I'll have to pay to get a new phone from Verizon. However, I realized that my dad has an extra jailbroken iPhone 4 that he never really used before. Can I request a SIM card for the iPhone and not have to pay for anything at all?
  • Is the iphone 5 from sprint a global phone? Does it have a removable sim card? I'm currently doing a lot of traveling to Kuwait and a couple co-workers have Verizon sim cards and all they do is take there sim card out and replace it with a Zain one (which is the local cell phone carrier) and use it locally for calls in Kuwait is that even possible with Sprint?
