Right. Just like a Core 2 Duo machine is basically the same as the Haswell-based machine. I mean, it's a little faster and the battery lasts a little longer, but so what? Can you really do anything on the latter that you can't do on the former?
For many people your (sarcastic?) example is totally right

. It has been some time now that most computers are capable enough for any of the basic tasks. You can perfectly use a web browser, email, office suite, view HD videos and many, many other things in a 2009 core 2 Duo Macbook pro or iMac (4GB RAM).
If you are not into the lastest 3d games or some other heavy software, Core 2 duo = Haswell from a usability point of view. You would notice a far bigger difference in performance by using a SSD than changing the CPU, and still you would do the same things. Maybe the battery life of laptops is the most important change.
It's not like new computers understand what you say like HAL 9000, or can proyect holograms that you can manipulate by hand, or can recognice your gestures or mood. The computers of 5 years ago are basically the same as now.
Now are faster, better, but not really that different. Same user interface, same input, same output. Sure everything is better in some degree, and that's great, I am not saying you can't notice the difference, but there was not any quantum leap that changes the experience or open new horizons.
