Popular computing languages do not in general have only one Open Source implementation, and do not get abandoned.
Slashdot videos: Now with more Slashdot!
Development with a proprietary language is ultimately harmful to your own interests, whether you make proprietary software for a profit or Free software.
The one thing every business needs is control. When you make it possible for another company to block your business, you lose control. Your options become limited. Solving business problems potentially becomes very costly, involving a complete rewrite.
The one thing that should be abundantly clear to everyone by now is that making your business dependent on Microsoft anything is ultimately a losing proposition. They have a long history of deprecating their own products after customers have built products upon them.
All Open Source licenses come with an implicit patent grant, it's an exhaustion doctrine in equitable law.
The problem is not patent holders who contribute to the code, you're protected from them. It's trolls who make no contribution and then sue.
Of course these same trolls sue regarding proprietary code as well.
Swatting is not like killing or stealing or doing drugs, picking up a phone and making a prank phone call is not on the same level as grabbing a gun and killing someone even if that phone call could have the same consequences. So the people that say "the parents always say they're a good kid" maybe they are a good kid because they would never pick up a gun and kill someone but they might pick up a phone and make a prank phone call and they should be severely punished for it.
I predict a lot of people will buy the 1.0 product and it will become obsolete quicker than you can say "apple stock". The 2.0 product might be more interesting. Can't believe they are charging 10k for the "higher end" watch. Bragging rights for rich folks, but rings pretty hollow considering what you get.
Apple Watch will probably go obsolete as quick as any iOS product, which takes a few years before they stop supporting it. The latest iOS 8 still supports the 2011 iPhone 4s. That's much better than Android, I don't think there are any 2011 Android devices that support Android 5.0 without rooting them.
