Consumer electronics are getting to the point where repairing them is not financially viable, nor really wanted for the vast majority of consumers. Yes, for laptops, etc - repairing them is still necessary, but on a £400 device? Especially when Apple offer a flat rate repair service, who can be bothered repairing them. For example, if I smashed my phone. I could take it to Apple, and have them replace the display for £80 on the spot. Or, I could buy a display for £30, some screwdrivers for £5, wait a week for them to get here, and take it apart myself, bearing the risk that if I broke anything else whilst in there, I'm £500 out of pocket.
Consumers couldn't care less about repairability - they want something that looks good, and works. Repairability = screws + clips = ugly and bulkier. If you want that thin iPad/laptop - you need to sacrifice the stuff nobody really cares about.
And like somebody has said - iFixit are just bitching because they're using an outdated business model. They moan like **** about the retina MacBook Pro's battery because they can't sell you a non-OEM Chinese copy - but never seem to mention that Apple will replace the battery, then separate and dispose of it in an environmentally friendly way for £150 ish. Which considering the price of the machine, and the process involved, is a bloody good deal IMO.
Maybe iFixit need to stop moaning and come up with an innovative way to save their business - if you're going to target the minority of consumers, you can't moan when the companies who form the backbone of your business stop targeting this minority. Also, let's not act like this new. 20 years ago, would iFixit have sold CRT tubes to the public for old iMacs?
