All Jobs is doing, is showing that he's scared. He spent a lot of time bashing Android (and Blackberry) in his investor conference call. You wouldn't do that if there wasn't some concern in there.
There was a lot more in that investor conference call not stated in the OP.
"We think the open-versus-closed argument is a smoke screen," Jobs said. "We're providing users with things that just work. We think that's the winning approach in the end."
I also find this amusing..
On Apple's earnings call, CEO Steve Jobs used popular Twitter client TweetDeck to make a point about Android's fragmentation.
"Twitter client, Twitter Deck [sic], recently launched their app for Android
. They reported that they had to contend with more than 100 different versions of Android software on 244 different handsets. The multiple hardware and software iterations present developers with a daunting challenge."
To which came this reply...
This morning, Iain Dodsworth, founder of TweetDeck, responded to Jobs with a tweet: "Did we at any point say it was a nightmare developing on Android? Errr nope, no we didn't. It wasn't."
If you look at the original TweetDeck post about all the Android handsets, and Android OSes out there, you can see the company is impressed by it all, not annoyed: "From our perspective it's pretty cool to have our app work on such a wide variety of devices and Android OS variations."
