I feel, as I write this on my late 2013 MacBook Pro, that it's powerful enough for most normal activities, read, browse, video calls, work on not too large data sets, etc. Anything that needs to run longer than I keep the laptop open can run on a different device, many programs are now web apps. The screen has a high resolution and the keyboard is good, if only battery and RAM replacements were easier it would be as good as new.
This is different to for instance my older laptop from 2008 or that before from 2004 - horrible screens, battery life, no fast wifi or USB.
But also compared to newer laptops, mine seems to get exactly the right balance between being robust and lightweight.
