I want to purchase either a lap top or iPad

When stores reopen as Covid-19 restrictions are lifted, for direct physical comparison, find a retailer that stocks the devices in which you are interested.

If comparing Apple iPad and Mac, then your best option will be an Apple Store. If you are looking for a PC, for direct sided-by-side, you’ll need to find an appropriate retailer.

I believe Best Buy’s are open as well as Walmart and Target, all of which are authorized resellers I believe, so you can get your hands on at least some devices there.
