(Fanboy downvote protection: I'm on my third year using a Mac. I love mag-safe. I love how it is usable out-of-the-box. I love the screen, the backlit keyboard. List goes on.
I was happy to see
* window resizing by any border and a
* decent attempt at fixing fullscreen and virtual desktops in Lion this year.
For next update I'm hoping for Apple to introduce a * "super-intuitive CMD-Tab that will let you switch
through all you *windows* in the order the were last
used" and
* "Menus now follow your windows" so there's less need
to move across a laptop screen and a full Cinema
Display to find the menu. Sounds familiar btw.
A sad thing Gnome keeps copying not only the good stuff but also the super annoying.)
