Re: Why is voiding of warranty a problem?
Having repaired a few iPhones recently, I'm starting to think they're not that bad. Once you get the screen off, it's all nicely done, and relatively easy to replace stuff, and you're right the extending tapes are a good innovation and preferable to glue.
What I object to though is the design for obsolescence of ultra-books. Want to extend the life-time of a laptop ? - upgrade the DRAM or the SSD. - hard to do when soldered down. I'm not convinced that this is down to space limitations.
