This is what I believe about missing the start button: Let's try to imagine that when MS came out with Windows 95 if it would have had the same interface as Windows 8 has now; and if all the newer editions had the same. Then after all these years, MS came out with what they called Windows 8 and the interface was exactly like Windows 7, everyone would be saying things like, "What happened to the tiles! I miss the tiles and wish they would come back." I believe that it's human nature. When we are used to doing things a certain way for a number of years, it's hard to change.
That's really not it, though--It'd be nice if things were actually as you suggest. But there are some critical differences to ponder:
...besides the fact that nobody with a
non-touchscreen device will be interested in 8.1's tile-based user interface (about ~1.4 billion people at Microsoft's last estimate of the total number of traditional desktops & laptops sans touchscreens running all versions of Windows and DOS worldwide.) So...
*Touchscreen user interfaces don't belong on non-touchscreen devices and monitors, period (painfully obvious to everyone except Microsoft, unless the company is actually doing an "8.2" as this writer-person suggests. Better late than never, Microsoft.) This would have been a much bigger disaster in 1995 as mass-market touchscreen devices weren't just grossly outnumbered as they are at present, they didn't yet exist.
*Not only are the tiles grossly incompatible with traditional desktops, laptops, and monitors, but they are ugly, their color schemes jarring and highly incongruent. Would have been even a bigger disaster in 1995 because then they'd have made even less sense than they do now...
*But it's not just the aesthetic qualities that have been changed in the Win8 tile-based ui, because that wouldn't make that much difference. Once you get used to it, even "ugly" can grow on you...
No, the main problem is that besides being ugly, the information conveyed by the garish tiles is
simplified to the point of being incomplete. Far too often in Win 8 the user must leave the RT user interface (tiles) and open up the traditional, Win7-style
non-touch user interface in order exercise the degree of control he'd like over his operating system because of the many things you simply
cannot do at all through the Win8 tile-based user interface.
*With the exception of the Start Menu,
all of the Win7 (explorer.exe-based) user interface remains fully intact within Win8.1. It's all there, and it has to be, of course, since the tile-based RT user-interface portion of Win8 is so incomplete. If the Win8 tile-based ui was as functional and informative as the traditional explorer.exe user interface then you'd certainly have a good point. Unfortunately, the two user interfaces are nowhere near "equal" in terms of the amount of control they offer the end user--Win8's tile-based user interface is grossly inferior to its explorer.exe-based user interface. Win8/8.1 has two user interfaces because it
has to, to function correctly. It's as simple as that.
Someone else mentioned Classic Shell 4.0.2, and I must concur that it is a must-have for Win8/8.1. It's of very high quality and it is free. It even allows you to turn off *all* the desktop hot corners and charms, if you want (8.1 only grants you very partial control on these things through Taskbar properties--can't turn off charms at all.) Or leave them on, if you want. I really like 8.1--it has completely replaced Win7 for me at home and at work. But, thankfully, I don't have to look at a single tile while reaping the benefits of 8.1! And why should I? I have no touchscreen, and have a zero desire to buy one. Good grief...
It's sometimes difficult to keep my monitor screens as clean as I'd like--but if I had to contend with greasy fingerprints all over them every day--uh-uh, no way! But also--my 2500 dpi-density mice are incredibly more accurate and precise than my pudgy fingertips will ever be! Johnny Paycheck should sing,
"You can take this touchscreen and shove it..!" I think he'd have a hit on his hands, no doubt about it.
