The MacBook Air was not really a "high performance" machine to start with though - you can't compare that with a ThinkPad :) And it was seldomly updated, so you could get very aged specs. If you bought a MacBook 2011/2012 you would typically get an HDD and between 4 and 8GB RAM. Software requirements/demands sky-rocketed shortly after that. On a non-Air you could at least upgrade this yourself, which gave the machine new life ("just like new")
