3 years is forever in a smartphone lifetime. No use complaining about something that is at the EOL anyway. I've got a droid X and droid X2 that are both used by kids on my Verizon plan. They work, but they are slow and laggy. But they work. I don't blame Motorola or Verizon for them not "being supported" anymore, I doubt that would make much difference in how they work at this point. Not many Droid X's out there anymore. They are so far behind the tech curve in hardware already, and of course the manufacturers and carriers want you to get a new phone every couple of years or more.
Apple supports for 3 years. The Lumia phones will get close to that.
EOL matters cause its when devices stop being supported by the manufacturer. It also matters if you like to resale your devices. Brands with better support tend to fetch a bit more, and that's part of the reason why iPhones retain value so well.
I never said anyone was complaining - don't put words in my mouth. The term EOL is pretty self explanatory in the context of this conversation.
The Samsung KK update for US S3 has been done for a while. It's just delayed due to the carriers - often the builds they push out are the same as leaked builds from months earlier and it's been that way since the OG Galaxy S. The time table the other person mentioned is inaccurate.
I don't think I said the phone stops working. I said it won't be supported to 3 years. I believe the thread asks that question, no?
Don't see what your old phones have to do with it. People are using iPhone 4 and old BlackBerry devices just fine still. We know that. That was the question the OP asked.
