Is Apple's latest operating system, Snow Leopard, a strong, reliable OS that demonstrates the versatility of Macs? Yes

That being said, is Snow Leopard an essential upgrade? No, not exactly.

The differences between Apple's "Tiger" OS (10.4) and "Leopard" (10.5) were very noticeable, and there were many improvements that made the upgrade worthwhile. Such as Time Machine, Boot Camp, Quick Look, and many more The bulk of changes between Leopard (10.5) and this latest release, "Snow Leopard" (10.6), are "under the hood" so to speak, and therefore the average user might not notice as much of a change as they'd expect with an OS upgrade. But then again, why fix a bone that's not broken? Leopard was a success, and Snow Leopard improves on it, without radically altering the user experience. The majority of improvements affect system reliability, speed, and resourcefulness. There is also Microsoft Exchange support, which is great for those who need it.

I bought the Snow Leopard upgrade knowing full well it wasn't going to be a drastically different OS, so I was by no means disappointed. I've been following the tech news regarding Mac and Windows operating system upgrades very closely, and am well aware that August's release of Apple's Snow Leopard and October's release of Microsoft's
Windows 7 are meant to provide additional stability and implement greater resourcefulness, rather than completely overhaul the user experience. This isn't a bad thing, since greater system reliability is more important than adding bells and whistles that ultimately take away from the user experience (i.e. Vista).

The most remarkable thing about Snow Leopard is simply that it can be installed on a Mac running Tiger. You do not need to pay the money to buy the boxed set to upgrade if you never upgraded to Leopard. This means that you can upgrade a Tiger computer to Leopard using this disk. It is up to the user to determine if they have an ethical problem with that; Apple certainly knew that this was possible when they released the software: they understand and use DRM effectively and always have. The fact it is missing here tells me that they are primarily concerned with getting Snow Leopard unto as many computers as possible as fast as possible. I am sure part of that is the desire to have Snow Leopard outperform Windows 7 which debuts in October.

So what do you get with Snow Leopard? The answer is largely performance boosts, although many of those are not really applicable (yet) since few (virtually none) third party applications use the performance gains offered by Snow Leopard. Similar to Windows 7s ability to load share between CPU and GPU, many of the changes in Snow Leopard will take several years for developers to really start to use and write programs for.

Relying on 64-bit architecture through the entire OS, Snow Leopard is essentially an upgrade for the future: as developers write programs that take advantage of the new, higher ceiling, end users like you and I will benefit. For now, most of the performance increases are only applicable to Apple's own software. However, that's not to say these aren't nice or useful, and in some cases very impressive:

1) Opening large photos is faster in preview mode

2) Quicktime uses significantly less CPU on all Macs regardless of generation. Older Macs benefit the most with as much as 40% performance gains.

I upgraded my Leopard-equipped late 2006 Black MacBook to Snow Leopard. I had it on pre-order all week and delivered on release date. It doesn't boast a whole lot of new stuff to it, but I like the new features it does have, and I love the fact that it takes up so much less hard drive space on my MacBook (I gained an amazing 29 gigabytes of space). I also noticed a pretty good speed boost after upgrading.

I really love the new Dock Expose, and how I can look at just one particular application in Expose instead of all the open windows in any given space. It makes finding things a lot easier. I also like the fact that you can now resize your icons in the finder. Dock scrolling (with magnification) and cover flow have been smoothed out greatly which makes it that much more attractive. Quicktime X is a pretty good movie recorder and the interface looks a lot better than previous version of Quicktime. Some other refinements are pretty nice as well.

64-bit support is amazing and I can see a difference in the apps that are now running in 64-bit (see the Activity Monitor for the apps that are running in 64-bit). Things just run smoother and faster.

Now, as far as some drawbacks of the system, this first one is a major one: when redesigning Safari, they made Safari and its plugins and completely separate processes, supposedly to improve the stability of Safari. Perhaps it did this, but as a result, it eats up far more CPU power than the previous iteration. This can result in your system slowing down, and I'm running into serious issues with heating (when using Flash for example, it eats up almost 70% of the CPU and I'm running around 150F, which is somewhat dangerous).
