>I don't think the same holds true for more involved repairs where a mobile phone made of (a few hundred million…) discrete and easily repairable transistors would be handy ;-) Yes, but the phone you are describing would be much easier to repair than an modern phone, with several orders of magnitude more transistors. Processor (Samsung Note 7 - Exynos 8890) Transistors - ~1 Billion (I couldn't find a good number for this, so I used a conservative estimate [1]). DRAM - 4GB = 8bits/byte * 4 billion bytes * 1 transistor per bit = ~32 billion Flash 64 GB = 8 bits/byte * 64 billion bytes * 0.5 transistors per bit (i.e. two bits per transistor with floating gate NAND Flash) = 256 billion transistors Ballpark total = ~289 billion transistors ;-) [1] https://en.wikipedia.org/wiki/Apple_A10#Design https://en.wikipedia.org/wiki/Apple_A10#Design
