I have over a hundred programs installed on my desktop machine and I use every one of them although most are rather infrequently. Since there is no way I'm going to remember the names of all of them, having a menu is essential for me. Scanning an alphabetical vertical list is one heck of a lot easier and faster than scrolling horizontally through over a hundred tiles.
In the APPS Screen everything is in alphabetical order, the same as the desktop menu even grouping each manufacturers apps together, you also have other options, including the most used apps thereby shortening the list to choose from. Again a useful aide memoire for those with memory problems.
Hopefully both options will be included in the final W10 release to the public which should then satisfy everyone.
Another is semantic zoom by pressing/clicking the minus sign on the bottom right of Start screen or Ctrl/Minus key, therefore less scroll. This all works great with either keyboard or mouse as well as touch.
Yes, if it were a sole desktop system as in the past we could/would, of course, stick with the old menu systems, but it’s limited with navigation and that’s not what MS is trying to accomplish. According to their data in the blog post below, most users used the Taskbar, Quick Launch, and/or placing shortcuts on their desktop. As time went on MS saw that less and less were using the Start menu. When they did, they were using it for infrequently-used programs. So they took the opportunity to port the Start screen over from the phone. This also gives users familiarity across devices, MS writes a unified OS across devices, and gives them opportunity to infiltrate the mobile market. Yes, MS’s sole motive is to sell products to make a profit. That’s called free enterprise and all companies exercise it.
As time goes on, I see more and more members switching over to the Start screen.
Designing the Start screen - Building Windows 8 - Site Home - MSDN BlogsAs we wrote about in our post on evolving the Start menu, after studying real world usage of the Start menu through a variety of techniques, we realized that it was serving mainly as the launcher for programs you rarely use. As more and more launching takes place from the task bar, the Start menu looks like a lot of user interface for programs you don't use very frequently. And the Start menu is not well-optimized for this purpose. It affords limited customization, provides virtually no useful information, and offers only a small space for search results. We found that people “in the know” who valued efficiency were moving away from the Start menu, and pinning their frequently used programs to the taskbar so that they could access them instantly in one click. We see this quite a bit on professional workstations where there are set of tools that all fit on the taskbar and are all used regularly—machines used by engineers, designers, developers, information workers, etc.
So, as evidence mounts that the menu hasn’t kept up with the modern way in which we use our PCs today, we've seen a growing interest in replacements for the Start menu (whether for touch, or mouse and keyboard). At the same time, we’ve seen an ever-increasing use of cumbersome notification tray icons (with ever-increasing menus and actions), and a continued interest in desktop gadgets that have yet to realize their potential.
In light of these realizations, we stepped back and reimagined the role of Start in Windows 8. We knew that we already had a powerful launcher for desktop programs in the taskbar. The Start screen is not just a replacement for the Start menu—it is designed to be a great launcher and switcher of apps, a place that is alive with notifications, customizable, powerful, and efficient. It brings together a set of solutions that today are disparate and poorly integrated.
