Well, boo. The touchpad is going wonky. This laptop, at four years in my possession, is otherwise holding up quite well.
The upgrades/replacements over the years include memory (to 16 GB), wifi (from b/g/n to a/b/g/n/ac, with Bluetooth -- which was not built-in), battery (a bigger, higher-capacity one), and hard disk (SSD of the same size -- 500 GB). ‎- Julian
The previous laptop went just over six years before replacement. ‎- Julian

I am about to Amazon Prime myself another mouse just to get by. Meanwhile, finding a replacement trackpad/touchpad might be too tenuous to be worth it. ‎- Julian
