Anyone
with eyes can see that the Apple iPad is dominating the tablet market
today. This is in large part due to the fact that as of now there are
still very few competitors on the market. That lack of competition is
changing quickly though with tablets running Windows and Android due
on the market soon.

Research firm Strategy Analytics reports
that for the quarter spanning July through September the Apple iPad
dominated the market with 95%
of the tablet market. The market for tablets over the quarter
swelled to 4.4 million units. The previous quarter was good for 3.5
million tablets according to the research firm.

Analyst Neil
Mawston said, "The tablet wars are up and running. Apple has
quickly leveraged its famous brand, an extensive retail presence and
user-friendly design to develop the tablet segment into a
multi-billion-dollar global business."

There are other
tablets coming to the market that will run Android, Windows, MeeGo,
webOS and the Blackberry OS making for many more choices over the
coming months. Android is expected to be very popular on tablets and
its scant 2.3% market share is expected to rise significantly in
Q4.

While Apple is dominating the tablet market, other major
brands are also looking to get into the tablet market. The world's
number two shipper of computers - Dell - will be getting into the
tablet
market in a big way in 2011. This comes from the mouth of
Dell CEO Michael Dell.

Dell said at an event in Hong Kong,
"We're going to have a significant number of new tablets in the
next year. There're lots of debate about the size of the market,
who's buying these devices, and those questions always emerge when
there's a new form factor."

Dell
also noted it's easier to develop software for phones based on the
Windows Phone 7 operating system than Android. There was no further
explanation provided for the comment, so we'd be curious to hear the
reasoning behind this statement.

Half the screen surface area. When you're interacting with a 2D display, it's the surface area that matters, not the linear distance. Assuming the same DPI, a 10" display can show 2x as many same-size icons as a 7" display.

Less actually. I can see you weren't very good in math. Doubling the diagonal will multiply the surface area by 4. As a result, to get twice the area, we need to multiply the diagonal by sqrt(2). That means that 7 * sqrt(2) = 9.899, which means a 7" diagonal screen will be less than half the total area for the same aspect ratio.

Well, yes, but you can't just square the diagonal to get the area... doesn't work that way. The ratios would be the same if we were dealing with perfectly square screens, but the areas would not (a 7" diagonal square screen would have an area of 24.5 square inches, not 49 square inches; and a square screen with a diagonal of 10" would have an area of 50 square inches, not 100). But these tablets have 4:3 ratio screens, which throws things off a bit.

The iPad has a 10" diagonal and is in a 4:3 ratio, so we are left with a 3:4:5 right triangle, giving the iPad dimensions of 6"x8" or 42 square inches. A 4:3 screen with a 7" diagonal will have a screen of 5.6"x4.2" or 23.52 square inches. This is 56% the size of the 10" screen. So I was off by a bit when I said "twice the size" but close enough.

If you look at the dimensions you will see that you can fit roughly two 5.6"x4.2" screens into the area of a 6"x8" screen.... it will overlap slightly in one direction (8.4 > 8), but be slightly shorter in the other direction (5.6 < 6).

6"x8" is 48"^2, not 42. Thus it is 23.52/48 = 49% the size (see my above post). To double surface area, multiply the diagonal by sqrt(2) and since 7*sqrt(2) < 10, a 7" diagonal (same aspect ratio) must have less than half the surface area.
