This isn't a spontaneous reaction to a new feature. I have had the opportunity to exploit mission control in the best possible way as I have been experimenting Lion for more than a month. That said, mission control is great but the old spaces NEED to come back. WHY? 1. Sense of direction: I usually handle spaces by alt+arrow keys. I also use cmd+number-keys to directly jump to them. But most of the time, one doesn't remember the screen number. There's always a sense of direction associated while moving to and fro; and to other spaces. There is no sense of direction for these new desktops in Lion. 2. Urgency to move: in a 3*3 grid, if you need to jump from space1 to space9, you would use alt+← array key. To move from space2 to space8, you would use alt+↓ twice and you're done. With Lion, you need to do that more than twice, plus the fact that there's no sense of direction, you would need to look at the content of the screen to adjust your desktop. So as soon as the number of desktops go above 4, things start to get bad and there's no comeback. 3. Only way to navigate: With random (last used) desktop adjustment, it gets worse. So the best way to use desktops in Lion is to remember the work spaces with numbers. cmd+5 , cmd+9, etc. I wanted spaces to look more like HyperSpaces. With a particular name for each space. Moving to a particular space would flash the name (& space number) of that space. For desktops, the name appears on the screen constantly (toggled through system preferences) [These features might be in development and might show in future releases] All I can say is that, with the new version of desktops in Lion, a serious amount of productivity is lost. With that comes, frustration and anger. The spaces in SL looks great. If they can somehow use a 2D arrangement with Mission Control, it'd be great. What do you guys think?
