Interesting, thanks for the link
I actually ended up pulling the trigger on the base model 14 inch that was announced today, but I'll probably still keep this laptop around as a tinkering device in the future. If not only because it's still fairly capable, but I've got some good nostalgia for it!
On the hardware side, you could open it up, clean the fan, re-apply thermal paste (after so many years, this will make a big difference) and maybe even upgrade the SSD if you feel like it.
That way, this laptop can easily survive another 1-3 years depending on your use-cases.
