I have an iPad Pro (2018) with A12X processor which at one point was a "holy crap this this is incredibly fast for how thin it is" device.
8 years later the local apps still run fast, but it struggles with web browsing.
Which is to say, you need a fast processor or web developers will out-bloat your device capabilities in a few years.
The processor is still fast enough, the ram is too small for modern web apps.
Yeah, devs using top of the line MBPs and taking a “works on my machine” attitude keeps web bloat on a constant incline.
I sometimes wish it were an industry norm for devs (a group of which I am a member) to be required to use a $300 Walmart special laptop for a week every two months.
