Re: Battling the UI
"What aids usability the most is not changing the UI."
With that attitude we'd all be using punched cards. The assumption that what is there now is perfect in every way and cannot be done better is always wrong. Even a "usable" UI can be improved. e.g. making the UI more discoverable, giving frequently used functionality greater prominence, adding new functionality which replaces previously cumbersome tasks, and aligning the UI to the tasks people use it for.
This can be seen in the evolution of the Windows task bar and start menu. Every release has added substantially to the behaviour of these key components. e.g. the task bar now lets apps be pinned to it so it doubles up as a launcher. It also shows thumbnails of running apps which can prove useful at times. The start menu tries to show apps that were used recently and does away with the hideous cascade of popup menus that users needed to navigate through in older versions to launch.
Not changing the UI or claiming it's usable is a cop out. If you don't want the UI to change, don't upgrade your OS.
Now onto Metro. The issue I have with Metro is not that it has changed. I couldn't care less if my launcher was tiles or a start menu providing that the tiles were functionally rich and useful as what it replaces. But it isn't. Metro doesn't do folders so it is kludged to hides icons for readmes, help, uninstallers etc., and to dump the rest of the icons in some linear tile arrangement that spans out horizontally over several virtual screens, losing all order in the process. And the tiles are massive making it a pain in the arse to use with a mouse. It's simply not designed to work with a desktop environment.
Some simple things could improve the experience immeasurably:
1. Implement tile folders and use for existing program folders. There really is no excuse for this omission even now.
2. Let users zoom in or out of metro to pack more tiles into their screen real estate.
3. Provide sort and multi select functionality so groups can be ordered around
4. Provide a compact mode which either overlays the screen so users don't lose context whenever they open a window
I expect that someone in MS land has plans to make it usable in Windows 9 but that is cold comfort for this release. Metro sucks.
