I got to see Yosemite yesterday on a guy's machine while waiting at the airport. I don't know if it was a developers preview or a bootleg of one of the DP sets. I suppose it doesn't matter. My conclusion was that some of the new features, once they get them working OK are good, in fact probably an asset. ....but then there are the changes to the user interface. Jonathon Ive said he was going to "pound it down" (the user interface, that is) and he did so...with a sledge hammer. This is the worst looking version of MacOS I've ever seen in my life. The folder icons are an obnoxious deep turquoise. The Red, yellow, and green window control buttons have no 3D effects and look more like some cheap drawing. Most 3d effects are gone from the title bars of apps. They're all flat and unsophisticated looking. It reminded me of an early version of Linux or maybe something more like Windows 1.0. Many of the icons have been "simplified"...appaarently they were too complicated for us, so now they're being dumbed down with obnoxious, high contrast colors and simpleton diagrams. THIS IS JUST PLAIN STUPID LOOKING!!! I've been a loyal fan of Apple for years, but face the facts guys, Steve Jobs is gone and the new head of the company and his "designer" are pretty clueless. The "good 'ol days" of Apple, as in during the '80's are over, and now it's rebirth and re-incarnation of the company by Jobs in the 2000's are over. All the stuff Jobs liked, like the skeuomorphic design of the recently fired Scott Forstall, was what made the early versions of iOS and OS X look great, but Ive apparently got Forstall fired and has been "correcting" first iOS and now OS X. FYI, CNET did a user rating of Ive's "greatly improved" iOS 7 and it got a 1.5 out 5 stars....all previous versions of iOS (from Jobs/Forstall) had ratings between 4.5 and 5. We obviously won't hear a bad word about Apple from anyone that stands to profit from advertising revenue but I'm afraid user rating tell the real story. Unless they change Yosemite to appear more like its predecessors, I would give Yosemite a rating of 0.5 out of 5 stars. You really have to see it to get the feel for how butt-ugly and stupid looking it is. I believe when my current generation of Apple hardware starts going south, the replacements will be non-Apple. Any ideas for non-Windows alternates? I'm thinking Linux, FreeBSD, etc.
