I feel for the Macbook side my main concern wouldn't be the increasing prices, but the combination with the fact that those things haven't really gotten better for some years. The entry level models with 128GB SSD are not better than was sold 3 years ago. I bought a 2015 Macbook Pro with 256GB, and the newest variant would be within the same speed rate, has the same amount of storage, and is more expensive. I would also prefer the screen as well as the keyboard of the 2015. The only thing that might be nice on the 2015 would be an (additional) USB-C/TB3 port.
