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.
2018 was iOS 12 which was a very good year for iOS optimization, things have been downhill since then.
I have 4 GB which is typical for these, and admittedly low by modern standards. The 1 TB model had 6 GB but was $1750.
