Meaningless
According to some data from Canalys, Android may have just taken the top spot in smartphone market share.
But smartphone market share data is really blurred right now. What everyone is looking at is smartphone operating system market share and that would be fine if it was, say, Blackberry vs Apple's iOS because the companies that make the OS make the phones as well. There is a direct correlation and the data is meaningful.
But with Android, the data becomes... Well, not useless. The trends are interesting but there's no practical meaning to it.
Market share for Android doesn't translate into money because Android is free. There's no monetary upshot to a high market share. It's just bragging rights. Meaningless.
Market share for Android also doesn't translate into handset market share because different manufacturers use it. Why, exactly, are we lumping those all together when they're all competitors? Meaningless.
Now, software platform market share is meaningful, except if we're talking platforms then why is the iPod Touch excluded? Because it's missing a GSM aerial? For a software platform, that exclusion is arbitrary and without a complete picture, the data is meaningless.
