We shall see indeed. The difference in pixel density between a 800x480 screen and 960x540 screen vs. a 960x540 screen and a 1280x720 screen is huge. Here's some math for you.
These percentage increases assume that the WVGA screen is 4", the qHD is 4.3", and the HD is 4.5". This also assume that all the displays are pentile, so that's not included in the calculations as it is a constant.
(960*540)/4.3 = 120,558
(800*480)/4 = 96,000
120,558/96,000 = 1.2558
125.58% increase in pixel density from WVGA to qHD.
(1280*720)/4.5 = 204,800
(960*540)/4.3 = 120,558
204,800/120,558 = 1.6988
169.88% increase in pixel density from qHD to HD.
The math speaks for itself.
Now just for ****s and giggles, let's compare a pentile HD screen to a non-pentile qHD
(1280*720)/4.5 = 204,800
204,800*.75(pentile) = 153,600
(960*540)/4.3 = 120,558
153,600/120,558 = 1.2741
127.41% increase in pixel density from a NON-PENTILE qHD to a PENTILE HD.
The math speaks for itself.
I've learned that the normal way to assess PPI is to determine the diagonal resolution (square root of the sum of the squares of the vertical and horizontal pixels), then divide that by the diagonal size.
The PPI of a 720p 4.5" screen is 326.
The PPI of a qHD 4.3" screen is 250.
Yes, that's a significant difference.
However, 300 ppi is considered the point at which normal human vision cannot discern further increases in resolution (depending on vision and distance). So, anything beyond 300 ppi may not matter to the average user. And, going from 250 to 300 PPI isn't nearly as big of a jump in perceived quality as going from, say 150 to 200.
Just doing the math doesn't guarantee anything, however. The math doesn't always "speak for itself." Different implementations produce different results.
Swearing to buy a device before anyone has even laid a hand (or eye) strikes me as iFan-type behavior. Telling people they are crazy to buy a different phone that none of us has laid eye or hand on is equally silly.
It's fine to talk about your expectations and beliefs, but another to say that they are generally applicable facts when they are not.
No, I am not a Bionic fanboy. I plan to buy a device in the next month or so. I had originally expected that to be the Bionic, but am now leaning towards the S2. I won't decide for sure until I actually get to use the devices themselves, however (and, may end up with something else completely different, if something better comes along soon.
Both will be quality devices, and both will meet most people's needs. But, preferences differ, and the tradeoffs I make may be different than the ones you make, but that doesn't mean I can call your phone "crap," or you mine.
