Then how is the Start Screen "hostile" if tiles aren't? Because that's all the Start Screen is.
A few reasons I can think of off the top of my head:
- Sideways scrolling is off-putting with a mouse
- Viewing all installed programs involves opening the start screen, right clicking on an empty area and having to click All Apps. Why no just have an All Apps button in the wasted space next to the User button.
- The All Apps view is dreadful anyway
- Lack of context menus, and their solution to get around it is fine for touch, not good with a mouse
- Having a open a whole new environment to search or open a program is jarring
- Organisation of files by group is fine, unless you want a lot of tiles. No sort of folders means scrolling.
- Lack of decent customisation options without 3rd party software
