Anyone who reports iPad as anything under 90% of the total tablet market is completely of base. 90% is what I consider a completely conservative estimate of Apple's complete domination in this space.
And while Android phones are doing markedly better, they're still doing crap compared to the iPhone. You have to consider than while estimates may be that Android commands 50%+ of the Smartphone market, Android phones account for nearly 100% of all smartphone models available. And well over 90% of all mobile phones of any kind in some markets/locations. With that kind of retail presence, 50-60% marketshare is, IMO, nothing to write home about. Google's reported activation numbers are fantasy and don't ever add up with the numbers reported by the carriers and manufacturers for sales.
I'd like to see competition drive usability, because IMO, while I feel iOS leads Android significantly in this regard, there is TONS of room for improvement. If you want a really frustrating experience, try doing anything at all with multiple iOS devices. There's no way to communicate between two or more devices built-in. Minimal amount if you are both connected to the same wireless network, but nothing if you're not. Even though all the devices have WiFi and Bluetooth. Want to use AppleTV without an existing wireless access point? Forget it, you can't. Think you might create an ad-hoc wireless network using your iPad or iPhone (or AppleTV)? Forget it, can't be done.
