Not a 'poor choice of words'. Maybe in 'your' eyes, yes, but certainly not in mine, sorry.
Are you dating Ballmer? Are you wanting his job? Is this the real reason Sinboy left? Was he threatened by YOU!?
If I move my cursor down to the lower left corner, and click, Start opens. I click a tile, an app opens, and if that app happens to be a Win32 app, I'm taken back to the desktop. I can scroll "down" Start using my mouse wheel. If I need back on the desktop, it's only a click or a key press away.
If I move my cursor to the top left corner, the task switcher opens, I click a window, and an app running in the background opens.
If I move my cursor to the top right corner, Charms opens.
I can still install the apps I need.
I can still work the way I want to.
Seems like the OS works perfectly fine to me. Completely usable.
I think you're looking for opinionated words like 'unconventional', 'inconvenient', maybe 'troublesome', etc...
