Yeah I'm still on my first coffee. Good morning and thanks for the math :-)

Here is the shocker: ACTUAL ARTICLE SIZE: 163 words, 971 bytes. That is a 0.034% of what was actually downloaded.

I know that browsers cache stuff. But a lot of these are dynamic resources that get loaded anyway. There is also the fact that caching on both the iPad and Android is horrible. So this really adds up on a mobile device.

So I think what I really want is an add-on or extension (I use both Safari and Firefox) that selectively changes the user agent to Mobile Safari.

Most sites are pretty good with providing iPhone compatible content, which is magnitudes smaller than the desktop version.

For example the techrunch page from my previous comment comes in at 33 requests and 122 KB when I set Safari to "Mobile Safari iOS 4.3.3 iPhone".

If only Safari on the iPad supported extensions :-/
