I agree. That's why I ended up loving Gnome 3. I screamed and bitched as much as the next guy when it was introduced. But I decided to give it a trial time of 2 weeks befroe moving on. It turns out, productivity was significantly increased with the new workflow. It's hard to break old habits. But it doesn't mean it shouldn't be done once in a while. Unity is terrible, taking the worst aspects of GNOME 3 without its really revolutionary aspects. I love the dynamic allocation of desktops. I cannot go back to a desktop that doesn't have it anymore. Managine multiple tasks is much easier.
I do miss the custom shortcuts, but again, probably with the size of computer and available applications, the search instead of categorize approach might be faster. And it's still easy to add shortcuts to favourites. And the fact that you just move the mouse to the corner to get the menu makes it fast and easy to reach even on a desktop. No need to think hard. The reflex comes quickly. The main pet peeve Ihave left is "why do I need to press ALT to be able to poweroff". That does seem like a gratuitous limitation, and not intuitively figured out, and therefore it's bad. Everything else in the new layout is intuitive, once you accept that your old habits are useless.
While it was easier to customize everything before, there is blessedly little left to customize now. Anyways, I did find my productivity increasing pretty fast after the initial decline. Now I wouldn't go back to earlier types of desktops. They feel like more work to get most things done.
