Your point makes a lot of sense and I do understand what you are saying. But I'm not sure consumers will agree in masses...
Back in the late 70's /early 80's (When I was moving between a C64, TRS-80, Atari 800, Apple II, Amiga, etc) it was obvious that the IBM PC would become the "Standard" in corporate computing. My little group of users (We called ourselves the "Pittsburgh Pirates"

) would meet once a week and dwell on stuff like this!. Since the IBM PC (and clones) were Corporate's world choice of PC, we wondered what machine would emerge as the Industry Standard "Home" consumer computer.... (I myself thought that the Amiga might become the "Consumer Industry Standard Computer")..
At the end of the day (as prices dropped and PC's were equipped with better video and sound cards) the PC also took over the consumer market as well.. Of course by the late 80's the Mac joined my PC in my home office as well and the 2 still sit side by side to this day...
I think we may see something similar in software as well. Why have something different on your home machine as you use all day at work? There are Non-Standard Project Management cheapo packages out there, but I use Primavera P6 at my job and it only makes sense to use on my home machines as well - - same goes for Excel....
I will grant you this, for folks who have a job where they don't use a computer daily, some of these non-standard consumer packages may be a viable option. I don't have a problem with any of them other than I can't risk a document not opening correctly on a clients machine...
Peace.
