My biggest objection to the tiles is also their size. They are practical for small screens so people won't "fat finger" selections but when screen size increases, finger size doesn't, so there is no need for tile size to increase. Finger size is a non-issue when using a mouse for selection instead of a touch screen, negating the need for tiles. For the same reason, I detest icons; like tiles, they consume too much screen real estate (I can have more programs listed onscreen with a menu list than with tiles). I keep mine shrunk as much as possible when I can't eliminate them; at least Win 7 allows me to do that, something one has fewer options to do so with tiles. Another major objection I have to tiles (and icons) is they are listed horizontally, making it harder to search for what one is looking for. Vertical lists are much easier to visually scan through, especially when entries are listed alphabetically. In a vertical list, the first letter of an entry is immediately adjacent to the first letters of the previous and following entries, making it much easier for the eye to follow. When entries are listed horizontally, the first letters become separated by the remaining text of each entry, making it much more difficult for the eye to follow.
Of course, I also feel tiles are so ugly it sucks.
All seriousness aside, I can understand the need to lighten an OS to enable it to be more functional on a low power devices such as a tablet or a smartphone and simplifying graphics, such as using the boring flat appearing tiles, is a valid way to lighten up the OS but doing so is an unnecessary and visually unpleasant step back on larger devices since they have more than enough resources to handle the more pleasing graphics, such as shading and shadowing. The virtual sticky notes on my desktop look umpteen times better than the boring flat tiles of Win 8. Displaying active apps within a tile causes it to become lost within the jumble of the other tiles unless one has only a few displayed.
There are objections I have to Win 8, such as hidden and fragmented menus, fewer options for customization, more restrictive policies, etc. Many of the changes in Win 8 from Win 7 were nothing more than change for the sake of change and either accomplished nothing new or actually hampered functionality.Edited by Lady Fitzgerald - 4/3/14 at 10:15am
