I'll admit that if there were an evacuation, I would consider taking my luggage. It depends if it were an evacuation for legal reasons or a dire emergency. Dire emergency, like the Asiana 777 crash at SFO or US 1549 in the Hudson River, I'd run for my life. If it seems somewhat precautionary, I'd take my luggage because it could be a fight for reimbursement or things that are hard to replace may be lost.

Lately, I've been wearing my coat before landing if the weather is very cold and I put some harder to replace things in my pockets, like the phone, keys, ID, and credit cards.

I also ask that the passenger in the window seat open the shades on landing at least half way so one can see if there's fire on that side. Only once did the passenger refuse. She was militant and probably felt she was a lifelong victim of discrimination so she had to insist on her way.
