This could be a good location, at least personally I think so. My time on here is maybe 15-20 minutes a time. Usually once or twice a week although the last week has been a bit more frequent. ;)
Something that I always admired about Apple (at least in the past) was that they were willing to make old stuff obsolete even when it was wildly successful. iPhone killing iPod is a great example of this.
That and just having a software base that was different from everyone else. It was funny, back when MS announced the change, here I was, a big Free/Libre software guy defending Microsofts proprietary browser with a journalist from Business Insider! Never did figure out if they did anything with that.
Always reminded that Nokia had one of the largest R&D budgets for mobile technology and got blind sided by iPhone and subsequent smart phones. Doesn't matter how ahead of the curve on paper you are if you cannot implement it into something that people want.
A good rule of thumb is that if your phone has a headphone jack, it also has FM radio. And whether it has a headphone jack depends on whether the phone aims to be waterproof.
Waterproof phone = no headphone jack = no FM radio. There are some exceptions, but it's more often true than not.
Every Samsung galaxy flagship from the S4 to the S10 had a headphone jack and was waterproof. This heuristic only works for recent models where headphone jack means it's a budget model and they've probably skimped on waterproofing.
the USB connector is a box that is not open to the inside of the phone, at least every one i've seen. I've even seen a couple of phones where the box that held the USB connector also had a speaker in it. I guess a headphone jack could be put inside of a similar box, but the main difference is all the contacts in TRR plugs are spring metal that are attached to the outside of the plastic housing and poke through, and that's if the spec calls for any sort of reinforcement. The simplest headphone jacks are just spring metal in empty space.
There are some hacky ways of getting a little distance on modern OS's, like using terminal based browsers. I'm thinking Links/Elinks but that will only get you so far and so long as the security certificates are available.
I cut my initial programming teeth on an 8Mhz (Maybe?) 8086 with 512KB RAM. Had the luxury of a 20MB HDD. At the time it felt like an ocean of storage. Nowadays it can be transferred around the world in less than a second.
"How much computing power do I really need on a day to day basis?"
I guess this is a kind of Computational Maslow's Hierarchy of Needs.
Basic needs can be covered by the vast majority of computer hardware. But once you get to large scale web browsing and gaming - more complex hardware is required.
The difference between a hermit living content in a cave and a billionaire in a 42 bed room mansion. Both could be happy but it really depends on their perspective.
It is kind of neat just how little power some of these older systems used. A big part was it was cheaper to make processors that used non-ceramic caps on them - but it limited the amount of power they could use due to thermal dissipation limits.
A good example in a similar fashion is the Super Nintendo. The power supply is rated to 7.85 Watts but it only uses roughly half of that when running. I believe the Neo Geo used 5 Watts peak. And these aren't physically tiny machines like a Raspberry Pi.
It is an interesting question. Apple hyper-optimized the OS for PPC when it was still relevant. Even modern PPC OS's with a good 20 years of additional compiler optimizations don't run those things anywhere near as well.
