Is it still worth it to buy an old MacBook (Air Early 2015), since Apple will drop Intel support?

Thinking of buying a used MacBook Air Early 2015 as a second laptop (that I can use on travels and I'm not afraid to get it stolen).

Specs:

MacBook Air A14 Early 2015 13" i7 8GB RAM 500 GB SSD Battery 100 Cycles Cost: 140€

Do you think it's a good deal? Was the cheapest I could find in my region.

How long would you think I would still be able to work on supported Apps with this device?
