You're right. When I open the bookmarks menu in Firefox, everything on my screen should go away and be replaced by a scrolling mass of big tiles. It just makes perfect sense.
Not an actual counterargument. Ignored.
The bookmark menu is a menu, not an application. The items contained in it are small hence the menu should be small, not fullscreen. Same goes for the start menu, the clue is in the name, it's a "menu", something you can flick through if you need to which tucks nicely away when you don't. I certainly don't want it to make picking an item difficult. That's why we use hierarchal views, because grouping similar things makes them easier and quicker to find. It's not even a complicated concept to grasp, I mean, do you keep all of your belongings in one big box?
The old start menu had two areas. A quick launch menu, which you can customize, and a "all programs" button which took you to the tree view. The new start screen has two areas. A quick launch menu which you can customize, and a "all programs" button which takes you to a tree like view, where you will find an Adobe section, with InDesign and Premiere, presuming you have them installed.
I wouldn't call an alphabetised list of everything installed on your computer even remotely "tree like".
Your earlier logic that smart people shouldn't become disoriented doesn't follow at all, and "Not an actual counterargument" is not an actual counterargument if you don't tell us why.
In theory it should also be doing some kind of negotiation before pushing power, such as ensuring that it has a connection to something that speaks USB on the other end (as opposed to, say, your finger, which doesn't), and that resistance is within the expected range for the cable. It's not "always on" current like an electric socket is.
You don't push power or current, you draw it. Your finger presents such a high resistance that I'd be surprised if you could even draw a microamp from a 100W@5V supply, let alone the full 20 amps.
My sister opened a computer store in Hawaii. She sells C shells down by the seashore.
