If it makes you sad because Apple is no longer devoting thousands of pixels at the top of each window to a big "drag this window" control, you'd better brace yourself, because the next step for many consumer applications is to have windows that cannot be dragged at all. This design looks like an iPad screen to me. Did the implications of Apple's stated mission to "make the Mac more like the iPad" not sink in? The iPa…
I highly doubt that that Apple will remove dragable windows. Their iPad-ification of applications is the full-screen mode that can be toggled. More likely: a bar-wide drag handler that takes precedence over widget clicking.
The problem is that app UIs are going to pick a paradigm and it's going to feel out of place if you use a different one. The dragbar being replaced is a pretty good example of this.
It's a lot of why I'm not particularly looking forward to Lion.
