And workplaces. Some people have more then one computer in the house. My 
partner can check her email when I had her over the computer. When I 
want to check my email when she is using it, I have to change the 
session, fire up Thunderbird (which eats away 20M), and change the 
session back.

Most people who use Thunderbird, yes. Different with OE, I am sure. With 
a thin client *everybody*.

But technically the UI (whether bloated or not) can be cached, and with 
Ajax/Frames, etc. there is not really a need to refresh the entire page. 
With smarter techniques (like automatically zipping pages), and 
techniques like transmitting only deltas (Google experimented with this 
some time ago) and better and faster rendering, the UI could be as fast 
as a normal UI. 

Isn't the UI in Thunderbird and Firefox created using JavaScript and 
XML? Isn't how future UIs are going to be made?

Maybe because a lot of users aren't really heavy users. A nice example 
(IMO) of a web client that works quite good: webmessenger ( 
http://webmessenger.msn.com/ ). It has been some time since I used it 
the last time, but if I recall correctly I hardly noticed that I was 
chatting in a JavaScript pop up window.

I rather have my email stored locally :-) But several webmail services 
offer a form to download email.

I read sometime ago that about 1/3 of traffic consists out of bittorrent 
traffic... If the Internet gets congested, new techniques are needed, 
like mod_gzip on every server, a way to transfer only deltas of webpages 
if an update occured (like Google did some time ago). Better handling of 
RSS (I have the impression that there is no "page has not been 
modified" thing like with HTML, or at least I see quite some clients 
fetch my feed every hour, again and again).
