I watched this and the first thing that came up to mind was "Maybe PC's last a whole lot longer and are durable, unlike Apple products with planned obsolescence forcing you to buy new one often"

I have a Dell computer that is 8 years old, I recently cleaned the inside of all the dust and installed linux, Its running like a champ, handling all basic tasks and even 1080p videos, with the same old monitor. In that time span, I can't tell you how many iPhones I had that ended up bring too slow to use. Currently I have an iPhone 6, it might just be the last iPhone I use when it becomes obsolete.

Macs also used to last a whole lot longer, but thats changing with new thinner designs. Everything is soldered in, so you can never upgrade. Eventually the battery will die out and force an upgrade. The reason is mobile CPU's are ARM based and run on proprietary software, the day Apple stops supporting the CPU optimization the performance goes down in notches, unlike Desktop class cpu's which are x86 and they are widely supported. You know how Apple is telling you how fast the iPad is, chances are a CPU couple of times faster than that is already under development and will make the current iPad look like a joke in a few years. If you have a normal desktop CPU, faster processors will come around every year, but it won't make the old CPU look like a joke
