is it normal for a laptop to have a 5 year lifespan?

Depends on the built quality I suppose.

My old personal HP laptop is on year 8 and still going. It's a little slow (even with SSD installed a few years ago) but still usable for most everyday tasks.

My work Macbook Air is going on year 6, still strong though it chokes on rare occasion.

I bought a Macbook Pro a year ago for personal use after seeing how good my work Mac has been even after all those years.
