"So we are very committed to the integrated approach, no matter how many
times Google tries to characterize it as closed. And we are confident
that it will triumph over Google's fragmented approach, no matter how
many times Google tries to characterize it as open.
"Second, 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 screen.
Let's start there. One naturally thinks that a seven-inch screen would
offer 70% of the benefits of a 10-inch screen. Unfortunately, this is
far from the truth. The screen measurements are diagonal, so that a
seven-inch screen is only 45% as large as iPad's 10-inch screen. You
heard me right; just 45% as large
"If you take an iPad and hold it upright in portrait view and draw an
imaginary horizontal line halfway down the screen, the screens on the
seven-inch tablets are a bit smaller than the bottom half of the iPad
display. This size isn't sufficient to create great tablet apps in our
opinion.
"Well, one could increase the resolution of the display to make up for
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 the present size. Apple's done extensive user-
testing on touch interfaces over many years, and we really understand
this stuff. There are clear limits of how close you can physically place
elements on a touch screen before users cannot reliably tap, flick or
pinch them. This is one of the key reasons we think the 10-inch screen
size is the minimum size required to create great tablet apps.
"Third, every tablet user is also a smartphone user. No tablet can
compete with the mobility of a smartphone, its ease of fitting into your
pocket or purse, its unobtrusiveness when used in a crowd. Given that
all tablet users will already have a smartphone in their pockets, giving
up precious display area to fit a tablet in our pockets is clearly the
wrong tradeoff. The seven-inch tablets are tweeners, too big to compete
with a smartphone and too small to compete with an iPad.
"Fourth, almost all of these new tablets use Android software, but even
Google is telling the tablet manufacturers not to use their current
release, Froyo, for tablets, and to wait for a special tablet release
next year. What does it mean when your software suppliers says not to
use their software in your tablet? And what does it mean when you ignore
them and use it anyway?
"Fifth, iPad now has over 35,000 apps on the App Store. This new crop of
tablets will have near zero.
"And sixth and last, our potential competitors are having a tough time
coming close to iPad's pricing, even with their far smaller, far less
expensive screens. The iPad incorporates everything we have learnt about
building high value products from iPhones, iPods and Macs. We create our
own A4 chip, our own software, our own battery chemistry, our own
enclosure, our own everything. And this results in an incredible product
at a great price. The proof of this will be in the pricing of our
competitor's products which will likely offer less for more.
"These are among the reasons we think the current crop of seven-inch
tablets are going to be DOA, Dead on Arrival. Their manufacturers will
learn the painful lesson that their tablets are too small and increase
the size next year, thereby abandoning both customers and developers who
jumped on the seven-inch bandwagon with an orphan product. Sounds like
lots of fun ahead.
