how much is multi used for web browsing and basic app use that isn’t editing video and photo and such
just day to day mail messages safari IMDb etc
For web-browsing, basic app use, day-2-day messages, safari, & IMDb. ANY iPad in the current line-up will be more than enough from the cheapest budget iPad to the most expensive iPad Pro. Heck, even the iPad Air 2 from 2014 (which is still supported by iOS15) is enough for these tasks, although the age and lower ram is starting to show.
So pick the size and features for the price you want to pay, and know with confidence that it will be enough to support your needs. If your needs change in the future you can upgrade at that point and get the newest specs.
