Just because it is old, does not mean it is outdated or useless.
It is because it provides such a well-thought-out framework that it has remained a defacto standard for common functions.
As for cutting-edge products... to the extent they provide functions not related to the common functions, of course they must design an appropriate interface; but it need not be radically different -- especially where new function is an extension of heritage function.
And even when not merely functional extensions, where new items have a relation to the heritage ones they can neatly fit within the CUA framework; thus making their access feel 'natural' to the seasoned user. Furthermore (and here is an
a-ha!):
if a new feature might fit in more than one place, it ought to be put in each area where it applies. Redundancy is a good thing.
Pardon the following rant, but you mentioned Office 2007 ...
Office 2007, on the other hand rather disregards the CUA for its new paradigm, which, although may be more efficient for new (and light) users, I find nearly unusable whenever I want to do for me what is routine, but which MS has decided is advanced, and hidden from me in new places, so I cannot find them easily.
While I acknowledge the 'research' that MS put into making the UI more user friendly, I totally decry their not offering with it an option to install the heritage UI for veteran users.
I would have thought that MS would have remembered the benefit of an alerntae UI, which it used effectively in the past to emulate WordPerfect and Quattro and other competitors interfaces (and which they reciprocated, or had started first).

It was one of the reasons that helped put MS-Office products in their now-dominant position.

And the lack thereof that may provide seeds for its downfall. :shock:
PS - I note that nikos has posted, that the UI for x2 will have to remain pretty-much as-it-is, using the heritage argument:
the great majority of users have come to learn it.
