Gosh, I love a good nerd debate but I always feel like it's a complete waste of time. Maybe this time is different? Perhaps if people whine loud enough, Apple won't make jokes about people with 5 year old PC's. They're probably trying to get a piece of that Windows XP market.
If you're using a > 5 year old XP box, there's a reasonable possibility that a new iPad Pro might satisfy your needs[1]; at least Apple wants you to consider it.
Instead the political correct "people" of the world debate endlessly about the nuances, while not adding a bit of value themselves. 'Do you fucking know that there are some people in this world who would be grateful for that computer?!". I don't think Apple was talking to them but don't let that stop you from getting on a soapbox.
Computers, and technology in general, are something that all kids should master before they're adults. Smartphones are great tools. Do some of that homework while you're between things. Learn another language (http://duolingo.com). Scratch that artistic itch, write a story, collaborate on school projects via the cloud, or work on a blog, even if no one reads it. Learn better English by debating on Reddit (not on HN, of course). Take lots of pictures and create movies.
Also, there's nothing wrong with a good Android phone. Learn the differences well, and don't pick one phone like it's a religion.
