Thanks for the reply and the link. I assume from your comment re the Tab, that you’ll sell that once the Andorid 3.0 tablets come out since that OS is optimized for tablets.

It’s a never ending cycle, isn’t it.

For me, my first tablet timing seems to be working out since the iPad 2 and Android 3.0 release dates are relatively close. I can sit back and wait for the dust to settle. Although, with all the Apple – Android vitriol that tends to take place, the dust may really get kicked up.

Thanks again

265 / 0.72 = 367 (close enough)

]]>PPI = Dp divided by Di

Dp = SQRT(Wp squared + Hp squared)

where

Dp is diagonal resolution in pixels

Di is diagonal size in inches

Wp is width resolution in pixels

Hp is height resolution in pixels

PPI = Dp divided by Di

Dp = SQRT(Wp squared + Hp squared)

iPhone 4

PPI = SQRT(960 sq’d + 640 sqr’d) / 3.5

PPI = SQRT(1,331,200) / 3.5

PPI = 1,154 / 3.5

PPI = 330

iPad 2 @ 9.7″

PPI = SQRT(2,048 sq’d + 1,536 sqr’d) / 9.7

PPI = SQRT(6,553,600) / 9.7

PPI = 2,560 / 9.7

PPI = 264

So, if the iPad 2 is 7″, but still has the aforementioned resolution increase, then PPI equals 366.

iPad 2 @ 7″

PPI = SQRT(2,048 sq’d + 1,536 sqr’d) / 7

PPI = SQRT(6,553,600) / 7

PPI = 2,560 / 7

PPI = 366

330 @ 3.5″ is better than 366 at 7″, but 366 @ 7″ is better than 265 @ 9.7″

]]>The article states that an iPad 2 @ 2048×1536 would have only 265ppi. I am assuming that would be if it stayed at 9.7 inches. The article later states that the screen may be only 7 inches. If the 265ppi does relate to the 9.7 inch screen, what would the ppi be in a 7 inch screen @ 2048×1536?
