This is so very true. Unfortunately, it also assumes some things 
which are still not true:

* Every visitor has a speedy connection
* Every visitor is on a powerful machine (so to speak)

The problem with the first is that, half the the US is still on a 
connection with speeds less than 6mbps. Downloading a whole page 
(such as your Facebook timeline feed, which can easily be 6+MiBs 
[see Akami link]) takes a full minute. That's pathetic for any 
kind of real-world business logic web app. Maybe okay for 
Facebook, but we could do better.

I can't even begin to tell you how many friends I have who are 
non-developers who complain on a daily basis that "they're phone 
has faster connection" or "Facebook loads slow" or "Gmail takes 2 
minutes to open".

The idea of pushing *everything* to the client to render (which 
often means payloads of 4+MiBs) is ridiculous and not being fair 
to over 80% of the world.
