I've been using Macs since before Tiger and while I have had a lot of problems with Lion, Fullscreen has changed my workflow for the better.
iCloud integration means I have been able to dump Google Calendar and Contacts. Changes made on my phone automagically propagate to my computer. iCal has gone from some weird app I started up a handful of times between 2005 and this year to being an auto-login application.
Different desktops with different backgrounds has improved my work flow as I immediately know "where" I am in my Desktops.
Ok, cool, glad you found three things useful. I had mm and would have liked iCloud on sl, so syncing hasn't been an addition for me, all the more so when I had, thank god for that btw, go to Dropbox and lose keychain sync. I appreciate your honesty for commenting that you had many problems with lion as well. Full screen I find useful to, but buggy and slow so far, plus many programs I used had a full screen mode anyway. I am not trying to play down its importance, it's a good addition. I concur i made a generalisation in my original post, to make a point, of course you can't have a new os, from apple for that matter, and find exactly zero new things helpful for most users. That wouldn't have been a poor release, that would have been akin to the titanic in os releases.
But by and large what I said is true, apple's additions, esp. core iOS inspired "features" almost no one has found them particularly useful, on the contrary most people have found them particularly annoying. I ask you in all honesty, if you could have sl with iCloud, would now consider downgrading, or upgrading rather to it? I know I would.
@nukkin. Well put, it was a ui gaffe, but i also think it also showcased poor core os development as well. It seems something is deeply broken with resource management, and the added ui features and layers on top make it even more apparent. Superb advances in ssd and CPU technology can mask it in some systems, but apple has been over reliant on these. 4gb macs are currently the minimum for running basic usage scenarios on macs, and this shouldn't be the case, all the more so when a good number of the line up, some airs for example max out at 4gb.
