I hate the Unity interface, but I can see where it's trying to get to.
The Unity bar on the left is a lot like a combination of the Start Menu and the Mac dock. It has a search feature for applications and files. And it has my main applications, the applications folder, and the trash bin. But I also hate the Mac dock, but I think the Unity bar is slightly better because of where it's placed on the left side of the screen instead of on the bottom on a Mac. Yeah I know I can customize the placement of the Mac dock.
I still hate having this dock. Yeah, sure it has easy access to my main applications. But after I've opened them what is the point of having the dock there. It seems like it's trying to be like a Mac and become super user-friendly. Macs are for the technologically retarded, installing applications by drag and drop.
The auto hide feature is damn annoying; every time I hover over there, it pops out.
When I right-click the applications folder/button, it brings up the types of applications I have. Now if I go under All Applications and then Installed, it brings up a the whole damn list. No, not even a list, a huge thumbnail gallery of all my applications. Maybe, I'll look through there to see what I have but I'm not going to use that often. And if I go through a category of applications, like Office, I have to go in a click the thing just to see what I have. I can't just breeze through it like in Gnome with the lists. Improvements need to be made here.
There lacks a bar for the current opened windows. And being an Ubuntu user, I think we all have lots of windows open. Using alt-tab is hard to manage for many open windows. There needs to be a bar for current opened windows.
The Unity interface has a lot of new shortcut keys, like SUPER-D to hide all windows, instead of clicking the Show Desktop button on the bottom left of Gnome. And I understand that using shortcut keys is faster than moving the mouse and clicking. They are trying to get users to use more shortcut keys, but it's weird that they put in this Unity bar to make things more graphical.
The new search feature is extremely useful for accessing applications quickly. It is similar to the Start Menu search on Windows and the Spotlight search on Mac.
I know Ubuntu is suppose to be fully customizable, but where the hell are the options/preferences for the Unity bar.
Unity sucks right now, and a lot of improvements need to be made.
