I don't know how it is in the UK, but here in the US, I have literally dozens of warranty options should I choose to buy one. None of them are "hidden" in any way, in ALL of them require one time lump payment, or recurring payments. I don't know how someone could NOT be aware of purchasing one so they are in no way hidden.
That said... Rather than paying $9.99/month for Apple care, I could just put that cash aside and save ~$120/ year. Assuming the first year is covered under standard warranty, then assuming the problem occurs during the second year, I should have ~180 squirrel away for a repair.
In my experience (buying mobile phones since they were literally bolted into cars in 1991), I've never once had a warranty issue. Meaning... over my phone buying life, I've saved $3,720. Which would be more than adequate to pay cash to replace a broken phone should I need to. Not to mention that for many scenarios other insurances may cover any loss, such as homeowners, credit card purchase insurance etc.
Long story short... if I can save as little as $10 by not having statutory warranties or buying aftermarket insurance, I come out way ahead. If I don't feel comfortable, there are dozens of other 3rd party warranties/insurances I can buy for my devices should I choose to.
Gotta say, I'm still firmly in favor of having a choice rather than some yahoo in Parliament thinking they need to make decisions for me.
