For the life of me, I just can't figure out the fanatical love of Apple. It has it's place, but it is not as good today as VMS was twenty years ago.
Nothing will ever be as focused and useful as VMS was. When you're so limited in compute power that you have to keep the crap off the machine, reserve time for the important stuff in batch jobs, and set real business priorities, computers tend to be more useful.
Apple, MS, Linux... Nothing's that focused. They all look like crack-addicted ADD poster-children compared to VMS or even CICS.
For Safari, Apple's just using WebKit as are at least two other browsers mentioned here. They're identical code almost, under the hood, rebranded.
Browsers are commodities now. The devs don't feel that way who haven't grown up and started using frameworks that handle their differences transparently in their code yet (or nearly so), and tons of businesses haven't (your bank, as one example), but folks just grab three or four browsers until they find one that works for them when they run across those clueless business who never understood the IETF, RFCs and standards.
The features that have "worked for me" on Safari for a long time now are the effortless bookmark syncing via MobileMe -- which was working a long time before other browsers had it even as plug-ins, let alone natively...
And the new "Reader" tools that get rid of the multiple pages of advertising crap and "click next" for 30 pages.
Plus the new "read it later" tool, which I always managed as a separate bookmark pool... Making it it's own thing is just natural as evidenced by Reddit, Instapaper and others like them.
Safari by itself is just another WebKit browser. With a couple of nice features. Used with three machines and two mobile devices, via Apple's services, it becomes seamless.
Foxmarks and their resulting "we're closing, no wait we're not" drama, Google's defunct bookmark sync service, and lately the enormously buggy XMarks out of the embers of Foxmarks, have all been used here too, and I've been burnt by all of them.
(Google pulling theirs was particularly lame considering all the far-less-useful stuff they do in conjunction with their good stuff.)
The Apple sync stuff has generally just worked.
What most people see as fanatical behavior is actually real appreciation for them not screwing features like that one up very often, if at all. It's nice.
There's certainly stuff they do screw up (Bluetooth on iOS), but there's a lot more that works than doesn't.
Problem is, you won't see it just on a single copy of the browser without their paid services in the middle and more than one device. It'd kinda be like buying only one of the old CICS services on mainframes from IBM, or MS Word without the rest of the Office suite. It works but it's not exactly all that cool.
They apparently "get that" too, since iCloud has been announced and the pricing is now virtually zero.
The integration they do to all their stuff works, really works... but it's a "you get what you pay for" kinda thing. People don't like to pay. That's normal.
Since VMS is pretty dead, you may want to give it a try.
They're the only game in town trying to optimize the hardware, OS, *and* Applications across traditional desktop environments and mobile devices to always work together and have a consistent UI.
MS makes stabs at it via document formats, but not the OS. Windows and Windows Mobile are significantly different creatures.
The end result for me is that the computers and mobile devices feel like they're getting more and more "out of the way" on Apple so I can get whatever it was I wanted to do, done... Without wasting time on computer "stuff".
Single multi-finger swipe, click icon from the full screen of them, application launches. No menus, no mouse "target practice" getting there.
Keyboard shortcuts that are mandated to be the same between apps and that work. Simple stuff. Paying attention to those details.
The true full-screen zero border migration that's just starting is refreshing too. When I want no distractions I don't have to go find twenty things and close them. Just go full-screen. They have some work to do there on multi-monitor support I hear, but on a single, it's grand.
In the end their stuff is very focused. If you're in the target user base, you're happy. If you're not, you wonder what the fuss is all about.
