A couple of weeks ago, I wrote about IDC's projections for smartphone operating-system marketshare in 2015, and came to the conclusion that the whole exercise of predicting phone sales that far in the future is pointless -- at least if you're doing so in a form which suggests a scientific approach.

Now IDC rival Gartner is making some 2015 predictions of its own. These ones are for tablets, and they forecast that Apple's share will fall under 50 percent, Android will surge to nearly 40 percent, and QNX, WebOS, MeeGo, and everything else will fight over the remainder of the market.

As ZDnet's Larry Dignan notes, Gartner doesn't break out any flavor of Windows in the above numbers, which apparently means that it thinks that Microsoft will be part of the "Other Operating Systems" that make up two-tenths of one percent of the market. Even an extreme Microsoft skeptic who thinks that the company will be a dismal failure in the tablet business might come up with a higher figure than that. Three percent, say?

You might be inclined to think Microsoft will flop in tablets; you might lean toward thinking that it'll figure out how to get back in the game. Either way, the fact of the matter is that we just don't know what'll happen. Nor is it clear how things will play out for any other tablet OS. Even Android has a negligible share of the market today, so predicting that it'll get to 38.6 percent in four years is speculative, not scientific.

And speaking of 38.6 percent, why do these forecasts always include numbers that extend past the decimal point? Gartner says that it thinks that iOS will have 47.1 percent of the tablet market in 2015, which translates into 138,497,000 iPads sold. Even if you're way smarter about this stuff than I am, it makes no sense to be that precise -- "about 50 percent" would be a better way of expressing this forecast, and even that is a guess that could well turn out to be way, way off in either direction. (At least Gartner doesn't say that Apple will sell exactly 138,497,261 iPads.)

I don't mean to bash Gartner here specifically any more than I intended to beat up on IDC. And there are mature categories where research companies might have a pretty good shot at looking ahead four years and getting it right, such as printers.

But tablets? The whole category is so nascent that talking about 2015 is like making forecasts in 1979 about the market share of major PC manufacturers in 1983. I wonder if Gartner did that?
