It seems like the guy is just trolling/venting, but I've had the same thoughts of "Apple's Vista".
I don't want to add to alarmist dirt tossing, but I've been running Lion since the first public betas.
My thoughts each release as it evolved, long before Jobs resigned, were "I don't think Jobs is around anymore, if he were, he wouldn't let this crap go".
LaunchPad, Mission Control -- these things were neat at first, but then they got annoying and cumbersome.
The new concept of scrolling is not intuitive, whenever I use it, I still get this momentary interrupt in my brain.
It would be intuitive if my fingers were on the screen scrolling, but since they're on a trackpad that's about a foot and 90 degrees away from the screen, it's not intuitive to me.
The UI is getting more Windows control panelish, things are needlessly being abstracted or hidden, but I need these things regularly, so now I have to sort through 2 more views before I get to what I need, or worse, launch Terminal and use 'defaults write'.
I'm not sure why the Dock is there anymore. It feels superfluous with Spotlight search and the non-suck portions of LaunchPad and Mission Control around.
Instead of an elegant transition between Mac OS X and iOS, it seems like clunky patchwork.
