Don't Wait If You Find Something You Like
If you find a tablet you love at a great price, don’t let iPad Air 4 rumors hold you back.
The iPad Air 3, 2020 iPad Pros, 2018 iPad Pros, 10.2-inch iPad, and iPad mini 5 are all excellent devices and they're worth a look if you don't think you can wait several months to buy your next slate.
Gather intel about all of these right now or in the near future. Who knows, you might find something you like long before the iPad Air 4 arrives.
