I must admit Gizmodo seems unnecessarily negative but I'm having a few doubts of my own. I picked up a refurb 2010 mini to play with ML. It came with SL. It was fast. Stinking fast. With 2 gig of RAM and a 5400 RPM drive it was fast. Compared to Lion on my aging Macbook, it was fast. Compared to Mountain Lion on that very same mini, SL was fast.
But the speed of an early beta is not the real source of my doubt. I'm just frustrated that Apple has voted so many relatively recent Intel Macs off the Mountain Lion island only one year after they voted Rosetta off the island.
I'm mildly annoyed by the new iCal and Address UI but it's not as big a deal as Apple's quickening pace of making old hardware obsolete. I would argue that Mac users need iCloud. iCloud really should be available on SL. In fact, I'd go so far as to say iCloud really should be available on Leopard. And these things should happen before somebody in Cupertino switches off mobile me. Perhaps this is an opportunity for a 3rd party app to sync from iPhone to Mac wirelessly on older versions of OS X. I guess the glaring issue here is Apple supports iCloud on Vista. Vista. The dorky OS Apple used in it's "I'm a PC I'm a Mac" commercials gets more current support than an OS Apple released after the last of those commercials stopped airing.
So I'm not as wildly negative about ML as Gizmodo, but I'm a bit worried that Apple isn't taking care of its older customers and oddly enough Apple is neglecting some of its more recent customers. To me the answer is to release updates for Leopard and SL that bring iCloud to those users who have older hardware and aren't ready to upgrade by June 1, 2012.
Now I turn to some of the criticism of ML based on how it works. In my brief usage, while I find it slow I find it every bit as usable as Lion or SL. I like gatekeeper and by default it's set to permissive. I bet if a bad malware threat emerged, Apple could switch the default to "identified developers only" by a software update.
As for creating a walled garden, I don't mind so much. I like curated computing. I look at my Mac like a "data appliance." Sure I could have bought a cheaper brand and spent my valuable time worrying about virus definition updates, direct x and dll heck but I opted for an environment where I'm not clicking on irrelevant warnings every 30 seconds and gatekeeper, if done right, could be another significant step in the direction of a quality "curated" desktop computing experience. If I was setting up a Mac for an 80+ year old senior, I'd switch gatekeeper to "app store only" and I'd be able to walk away secure in the knowledge my phone wouldn't be ringing the next morning with "i can't print" "i can't connect to the internet" "i can't get email" "i cant boot up" like a windows user might run across.
The ability to optionally "make a Mac run like an iPad" is a good thing to a person like me that spends a good chunk of my time helping family members with computer problems. And no, my Mac-using family members never call me but there are at least half a dozen who refuse to switch because they are afraid they can't "learn" OS X. In an iOS-like OS X, there's nothing to learn.
So while I'm frustrated with all the haters saying ML is the end of the world for Apple, I'm disappointed Apple doesn't offer iCloud to users on older OS/hardware so they can switch at a time of their own choosing rather than losing services (mobile me) they enjoy today.
