I completely agree with you narrow. The Agenda is NOT a good substitute. At best it's a kludge. You have to scroll around, and because the Date headings are in a small type face, albeit capitalized, it is harder to use. Why not make the dates in reverse color - with a black text on a gray bg running across the width of the agenda. Would be much better.
But, still, would not be a replacement for the Week view. Personally, since I use this for both work and personal matters, I'd also like a Work Week option.
I've managed to get used to using the Agenda display, but it requires too much scrolling, IMO, and is not well laid out (see above).
I imagine that one reason they aren't offering a week view, is that it would only work in landscape. Perhaps that's harder to implement in the context of the pivot display that is there now.

I'm sorry that you don't see the benefit of seeing the entire week at once, as opposed to just a few hours that can be shown at once with Agenda or Day. I, however, see great benefit in it and used it all the time with Android. It is my preferred view for my laptop calendar as well.
