About time.
Document Model
One step forward, one step backward. I feel this has become unnecessarily complex. I would’ve preferred a simple “Save as” option. It’s good to know that Apple knows they should address this but they’ve made an even bigger mess in ML.
iCloud
iCloud is still at least 1 year away from where it needs to be. The current “on iCloud” open/save dialog is a step forward but the lack of an “iCloud System Finder” is felt in the way things work in ML. But I think Apple is looking for a better, easier solution.
Skeuomorphic
I have traditionally been a sort of “modernist” in architecture and design (specially app design): i hate skeuomorphic app designs with a burning passion. I think some of Apple’s are kind of pretty and if the whole system (including 3rd party apps) adopted skeuomorphic designs it could be pretty. As it stands, it’s an anachronism better suited for Monty Python than an actual Operating System. That said, some improvements where made, namely the sidebar for calendars on iCal.
Notes
I’m probably not going to use them since I’ve been using nvALT and Evernote for years (and recently switched to Notesy on iOS). But it’s a huge improvement for new users and who knows, maybe somewhere down the line I might use it for something.
Power Management
I would really like it if Dropbox would use DarkWake to do its indexing. It’s the only background task that’s not so “backgroundy” - it handicaps my MBP like no other app.
Mission Control
The new option to display windows independently of application will make a world of difference in its usability for me.
Sharing
About time this came to OSX.
Dashboard Search
Minor detail, huge improvement. But I think I’ll stick with spotlight (or switch to something like Alfred ).
