This is true. I've been buying them for 3 decades and that's never changed, however the last few years certain aspects (like the CPU) have rapidly slowed in development. Whilst other areas of course have gained a good lick of speed. Monitors being the bane of my decision making right now!
On the bright side I used to buy 1 a year, every year. So I should just get on with ordering something "mostly what I want" and get another one in a year / two ...
