Went to Apple Genius Bar yesterday. Said, effectively, that my gf's iPhone 5s days were numbered, and that most mobiles will probably only last 2 years. Although he added that's mostly due to phone contracts these days.
He also tried to explain why the EU's 2 year warranty didn't apply to Apple stuff.
The only thing he said which sounded remotely true, was that the screen on the iPad (iPad 2) wasn't easily fixable because of the need to keep it thin and light. If it was made to be repairable, the iPad would be thicker. Which at least sounds reasonable.
