Mac OS X Tiger 与 Leopard 使用普遍性 - 有研究吗？
我需要决定是否应该支持 Mac OS X 10.4 / Tiger，这个决定可能取决于仍在运行 Tiger 的 mac 用户的百分比。我在互联网和苹果开发者网站上都没有找到任何太可靠的东西。让我们忽略即将发布的 Snow Leopard 及其对 Mac OS 版本使用分布的影响。
有谁知道一项可以提供见解的研究吗？关于如何解决这个问题还有其他建议吗？如果您引用任何数字/百分比，请注明来源。
I need to decide whether I should support Mac OS X 10.4 / Tiger, and the decision likely hinges on what percentage of mac users are still running Tiger. I didn't find anything too reliable on the interwebs nor on Apple's developer website. Let's ignore the impending Snow Leopard release and it's impact on Mac OS version usage distribution.
Does anyone know of a study that might provide insight? Any other suggestions on how to figure this out? If you quote any numbers/percentages please include a pointer to the source.

OmniGroup 跟踪使用其软件更新程序的系统配置。目前Leopard 的比例大约为 60/40。
OmniGroup keeps track of the system configurations that use their software updater. The current split is roughly 60/40 in Leopard's favor.
请记住，从之前的版本来看，一旦 Snow Leopard 发布，苹果可能会放弃对 Tiger 的官方支持，这应该是任何一天。
Keep in mind that, judging from previous releases, Apple will likely drop official support of Tiger once Snow Leopard is released, which should be any day now.
这实际上取决于您的软件的用户受众（他们是否可能升级）。我没有进行研究，但考虑到每次重大更新的成本，我确信有许多非高级用户仍在使用旧版本。
It really depends on what user audience your software has (whether they're likely to upgrade or not). I don't have a study, but considering how each major update costs money, I'm sure there are many non-power users who are still on older editions.
您最好只针对 Leopard，尤其是 Snow Leopard 将在本周末推出，并对关键技术进行大量更改。 Apple 的行动速度非常快，很快对 Leopard 的支持将成为您的传统支持。
You're better off targeting Leopard only, especially with Snow Leopard coming out at the end of the week with a lot of changes to key technologies. Apple moves pretty quickly and soon enough supporting Leopard will be your legacy support.
