I think your colleagues have good points about the memory usage implications of this technique and also the option to use SPDY. I think that SPDY is the better solution for this if I understand it correctly in that SPDY tries to provide a single http request for delivering multiple files.

Of course, but most people only view one page. Some select few go on to view more pages.
A large majority of my visitors come from a twitter link, a HN link or a google search. They rarely read more than one page.
That first impression is important.

the small gain initial load time is more than butchered by the awfully longer repeat view time.
