ADAM vs iPAD

[Kibje]

Hi All!

I did some proper calculations, using trusty ‘Pete’ and came up with this nice comparison between the Adam and iPad.
I am trying to keep it as honest as possible so sometimes the iPad will win and sometimes the adam.

Size in mm.
adam: h= 126, w= 224
ipad: h= 148, w= 197

Number of pixels.
adam: h= 600, w= 1024
ipad: h= 768, w= 1024

Maximum resolution and size of a 16:9 video, when watching on device screen.
adam: 1024×567, size: 224 x 126 mm
ipad: 1024×567, size: 197 x 109 mm

Maximum resolution and size of a 4:3 video, when watching on device screen.
adam: 800×600, size: 168 x 126 mm
ipad: 1024×768, size: 197 x 148 mm

Of course there are many other area comparisons that can be done.
One which interests me in particular has to do with the default whitespace (margin) surrounding a a4 PDF (of which i read quite a lot as technical review). Since we do not need to show this whitespace, a rectangle is left over which we do want to show. This rectangle is (when we take a 20 mm default margin on all sides, very common) 170 x 257 mm. With some calculation we can see which device can show us the largest A4 paper.

Maximum size of standard A4 PDF shown on device screen.
adam: 126 x 190
ipad: 130 x 197

The iPad does not have an PixelQI screen (so forget reading outdoors) but with its higher DPI and slightly larger screen area it should be a better e-reader replacement in poor lighting conditions.

Good post Kibje, I don't think that anyone had looked at the devices from that POV. However, may I suggest moving it to this thread since it might interest the folks there who already started comparing them?

Will do
