I had a Thinkpad T440s that had a ridiculous battery life. I think I picked I picked it up on eBay for like $300 4 or 5 years ago. I tinkered with it and ended up breaking it and didn’t have time to put it back together/fixed up but that thing was a dream. I have a “desktop replacement” PC that’s huge and unwieldly and I wish I just kept my T440s with an upgraded display and like 4 days of battery life.
Hearing about this got me to reevaluate whether I needed Prime and I ended up cancelling altogether. Just a heads up, if you cancel mid-subscription (I was on the yearly plan) you get the option to cancel service immediately and refund what you didn’t use. I was supposed to re-up in May and ended up getting $63 refunded.
