Microsoft rearranged the keys on the function row of the keyboard. That's disappointing because I got almost seven and a half hours on the previous model and because Microsoft touted battery gains with this update. I typically got around six and a half hours' worth of battery life on the Surface Book 3.
The bezels around the display look a bit dated now, for example, as other Windows laptops from makers such as Dell have nearly eliminated screen borders. The Surface Book could use a little design refresh. There's something to be said for an approach like Apple takes with the iPhone, where it updates the internals regularly, but also rolls out visually obvious new designs every couple of revisions, so people will always know who's carrying the latest model. If you're into showing off your new purchases, then you probably won't appreciate that the Surface Book 3 looks and feels almost exactly the same as the products it's replacing.
