Here’s an interesting post on what Steve Jobs thinks of the other competing mobile platforms out there. Though very insightful, I would not 100% agree on many of the viewpoints. They are obviously biased in favour of Apple :)
He spoke about Blackberry, Android, The Tablet Market, Nokia, Smartphones, etc etc. Here’s his full take…

On BlackBerry

“We’ve now passed RIM. And I don’t see them catching up with us in the foreseeable future. They must move beyond their area of strength and comfort, into the unfamiliar territory of trying to become a software platform company.”
“I think it’s going to be a challenge for them to create a competitive platform and to convince developers to create apps for yet a third software platform after iOS and Android.”

On Android

“Last week, Eric Schmidt reiterated that they are activating 200,000 Android devices per day, and have around 90,000 apps in their app store. For comparison, Apple has activated around 275,000 iOS devices per day on average for the past 30 days, with a peak of almost 300,000 iOS devices per day on a few of those days. And Apple has 300,000 apps on its App Store.”
“Google loves to characterize Android as “open,” and iOS and iPhone as “closed”. We find this a bit disingenuous, and clouding the real difference between our two approaches.”
“Android is very fragmented. Many Android OEMs, including the two largest, HTC and Motorola, install proprietary user interfaces to differentiate themselves from the commodity Android experience. The user’s left to figure it all out. Compare this with iPhone, where every handset works the same.”
“Many Android apps work only on selected Android handsets, running selected Android versions. And this is for handsets that have been shipped less than 12 months ago! Compare this with iPhone, where there are two versions of the software, the current and the most recent predecessor, to test against.”
“In reality, we think the open versus closed argument is just a smokescreen to try and hide the real issue, which is, “What’s best for the customer – fragmented versus integrated?” We think Android is very, very fragmented, and becoming more fragmented by the day.”

On the smartphone market

“I think right now it’s a battle for the mindshare of developers and for the mindshare of customers, and right now iPhone and Android are winning that battle.”

On Nokia (and developers)

“Nokia makes $50 handsets, and we don’t know how to make a great smartphone for $50. We’re not smart enough to have figured that one out yet, but believe me I’ll let you know when we do.”
“Most of them [developers] will not follow you. Most of them will say, ‘I’m sorry, but I’m not going to write down a watered-down version of my app just because you’ve got this phone that you can sell for $50 less, and you’re begging me to write software for it’.”

On acquisition possibilities

“We strongly believe that one or more very strategic opportunities may come along, that we are in a unique position to take advantage of because of our strong cash position.”
“We don’t let it burn a hole in our pocket, we don’t allow it to motivate us to do stupid acquisitions. And so I think that we’d like to continue to keep our powder dry, because we do feel that there are one or more strategic opportunities in the future.”

On the tablet market

“I’d like to comment on the “avalanche” of tablets poised to enter the market in the coming months. First, it appears to be just a handful of credible entrants, not exactly an avalanche. Second, almost all of them use seven-inch screens, as compared to iPad’s near 10-inch screens.”
“The screen measurements are diagonal, so that a seven-inch screen is only 45 percent as large as iPad’s 10-inch screen… While one could increase the resolution of the display to make up some of the difference, it is meaningless unless your tablet also includes sandpaper, so that the user can sand down their fingers to around one-quarter of their present size.”
“Every tablet user is also a smartphone user. No tablet can compete with the mobility of a smartphone… The seven-inch tablets are tweeners: too big to compete with a smartphone, and too small to compete with an iPad.”
“iPad now has over 35,000 apps on the App Store. This new crop of tablets will have near zero.”
