Ok.

Your options are still.

Show up on your first day with a laptop.

Show up on your first day without a laptop.

My suggestion stands.

Odds are you can get your job done with a 500$ laptop if push comes to shove.

Now of course you can show up without a laptop and get into a nasty argument about them needing to provide you equipment. You’d be right, but they’d have the option to fire you on the spot. Even if this isn’t technically legal, you don’t have much recourse.

It’s up to you.

Everyone else here is going to keep downvoting me, and not a single one of them will help you find a new job.
