But it seems to me you are assuming again. You are assuming how they are using the device. With Nintendo's products you are not assuming, you know what they are using it for.

I don't think I'm getting my point across very well. I'm not disputing that a large number of people use their iOS devices for gaming, which is good.

I'm just saying that you cannot necessarily compare two devices on a 1-to-1 basis using sales numbers if the two devices are not comparable 1-to-1 in their usage. The iOS devices are versatile in nature and are suitable for multiple tasks. It's not proper to compare every single sale of an iOS device against every single sale of Nintendo's products. You can make estimates and guesses but I don't feel a 1-to-1 comparison can be made nor be fair.

To make a comparison like this I'd rather know the numbers of game titles sold per device. That comparison works for me because the purpose of buying the game is to play it, nothing else.

I specifically did not make a 1-to-1 relation on sales, instead stating "the number who play games on the device". I subsequently put up a range so large (100-250 million) that it'd be hard to call it an assumption.
