since 2005 i've anxiously awaited every OSX release and updated ASAP.
this year 2011, OSX 10.7 is a disappointment.
no resolution independence
no changes to awfully old Finder interface (still no CUT & PASTE)
see: http://totalfinder.binaryage.com/
and: http://www.cocoatech.com/
no themes - still the ancient Aqua
no new file system like ZFS/UFS
no advanced multiple-file copy behavior (etc. stacked paused queue for maximum speed - alike Windows 8)
awful mission control - bring the spaces back as in 10.6
useless lauchpad - who the hell needs that, you have APP stack on dashboard already!
these are the main issues that are on my mind.
How does that relate to 10.8?
And, not everyone has an "APP" stack on dashboard. I happen to use Launchpad a lot.
