Re: Never enough..
"beta testers, how many million of us does MS have? but still it takes years for something obviously ill considered to be changed."
Perhaps they are harking back to the original meaning of beta test -- the software is pretty much in its final state but we need to find the rest of the bugs. It's far too late by then to be thinking about architectural changes. You will see bug fixes and you will probably see cosmetic changes, like moving buttons around or trying out a few new colour schemes. Hmm, actually, that does pretty much describe the last six months of the Windows Insider Fast Track.
The real question is just how they went so badly wrong in the meetings that decided on the original architecture. I mean, how did *any* group of people who have used computers before reckon that is was acceptable to have hidden UI, or for half the necessary controls to be in one "control panel" and the other half to be in another, or (as already mentioned above) to use the same UI on a 4-inch touchscreen as on a multi-monitor mouse-and-keyboard setup?
