It seems they are not counting iPod touches / iPads. For a developer, total ecosystem size and probability that owners will buy apps is a little more important.
On a tangent, Nintendo Wii had really good sales numbers, but I wonder if the number of games bought per console was around the same amount as the PS/3 or XBox 360? I have my doubts. I think the game console market shares is a more probably predictor of phone market share than PC sales (i.e. no highlander).
The article clearly mentioned, "mobile operating system". iOS powers iphone, ipod, ipad, etc.
On a tangent, there hasnt been much talk about how the corporate policies have evolved since the smartphone era. I bet we will see companies rolling out custom android OS deployed on stock hardware such as EVO given out to employees, with restricted permissions and access.
Well, I would dispute the numbers then. It doesn't look at all like the iPod touch is really given consideration.
I could see that if Dell was a bigger android player, but it really takes a vendor with sales / support leading the charge. HP would be a probable except for the Palm purchase.
It may have mentioned "mobile operating system", but the figures are clearly excluding something. I think there's about 100mm iOS devices sold to date, but these figures show less than 50mm for 2010
You're interested in gaming software tie ratios. Here's a reference, but basically: Wii had a strong tie ratio for the first year or so, then was overtaken by the PS3. 360 dominates both, if I recall correctly (can't see the article at work).
