A chunky case would undo a lot of that.

So my recommendation for you would be

fit a high-quality tempered glass screen protector on day one.

Use the phone without a case every week

while you're still within Costco's return period.

If you find yourself feeling nervous every time you put it down,

buy an ultra-thin case, not a bulky protective one.

That way you get to discover whether the air's design

is actually what makes you love it.

One final thought.

Because you've bought it from Costco and can return it if you're not happy,

don't stick a cheap, sticky, ill-fitting case on it

before you've experienced it properly.

Spend a few days using it as intended.

If you decide to keep it,

then choose protection that preserves the qualities you bought it for.
