I noticed in the Samsung Galaxy Tab 10.1 comparison videos that the iPad 2 screen appears wider than the 10.1's.

Maybe its just my eyes playing tricks on me, but is it possible for the iPad 2 screen to actually have more viewing area than the 10.1's because its wider (in portrait mode)?

Thanks

I depends on what your viewing. If youre looking at a widescreen movie, then no. But if your looking at a PDF in portrait mode then yes. So it just depends on what you plan on using the tablet for.

Lets let math tell us the answer.

Area is Length x Width. Unfortunately screens are dimensioned diagonally. We have some clues that help.

iPad's screen is a 4:3 ratio. 9.7" diagonal
Samsung's screen is a 16:10 (8:5) ratio. 10.1" diagonal.

Area of the iPad's screen is easy to find if you know that a right triangle with 3" and 4" sides has a third side of 5". So 9.7 / 5 = 1.94, and 1.94 x 4 = 7.76, while 1.94 x 3 = 5.82. Area = 7.76 x 5.82 = 45.1632 sq. in.

Area of Samsung's screen needs a different strategy. In this case we might use A^2 + B^2 = C^2. 64 + 25 = 89. SqRt of 89 = 9.433981132056604. So 10.1/9.433981132056604 = 1.070597858806424, and 1.070597858806424 x 8 = 8.564782870451389, while 1.0705978588o6424 x 5 = 5.352989294032118. Area = 8.564782870451389 x 5.352989294032118 = 45.84719101123596 sq. in. In other words, the total screen area on the Samsing is only slightly greater than that on the iPad. 45.85 vs 45.16.
