This looks really cool, but the author... is... replacing their laptop every year ? Like, I'm writing this on an 8 year old MBP that has survived as my round-the-house driver because it still does everything well. My daily driver is getting on a bit now (3yr) and my desktop only just got replaced after 5 years. Forget the cost, but the waste!
Not really that uncommon especially with a MacBook Pro where a new one is released...every year.
How much sense it makes, that's another story.
