Q. the Samsung Galaxy S2 for T-Mobile, the Samsung Galaxy S2 for AT&T or the Samsung Galaxy S2 Epic Touch 4G for Sprint.
I am a AT&T customer and the AT&T phone has the smallest display out of the three but seems to be the smoothest and most fluent one.
A. All three U.S. variations of the Galaxy S2 will have the same screen resolution of 800x480, which is also known as WVGA (Wide Video Graphics Array). The screen size does vary between 4.3" for AT&T (and International) and 4.5" for T-Mobile and Sprint.
The problem with just increasing the screen size without also increasing the screen resolution is that the pixel density, and thus the quality of the image to your eye, is degraded/reduced. In lay terms, the same pixels are basically "stretched" across a larger physical space.
The metric that describes this is PPI or 'points per inch' which is calculated by combining the screen size and screen resolution.
For those geeky enough to care, the calculation is PPI = diagonal_pixels / diagonal_inches where diagonal_pixels = sqrt(pixel_width^2 + pixel_height^2) - basic Pythagorean theorem.
Doing the math reveals that the AT&T version will have a pixel density of ~217 ppi compared with ~207 ppi for T-Mobile and Sprint. That is approximately a 4.6% difference in pixel density.
The tradeoff between the two is pretty even from a mathematical standpoint - a 4.4% increase in diagonal size compared to a 4.6% decrease in pixel density, so it depends on what matters most to you as an individual.
I am going with the AT&T version for two reasons.
First, I like the way the 4.3 inch size feels in my hand and I can do just about anything with the phone without needing two hands - the 4.5 inch Infuse started to get a little unwieldy and I have large hands (I'm well over 6' tall).
The second reason is that pixel density below 300 ppi is still noticeable to the human eye, which is why companies like Apple refer to displays with > 300 ppi as 'retina displays' or other trendy terms like that. Put another way, as displays improve toward 300 ppi, they will look increasingly good to the eye but increases beyond that don't matter much. It is unlikely Apple will release a phone as large as 4.5" without retaining the 'retina display' qualification as they consider visual quality vital.
If T-Mobile or Sprint were to increase the resolution to qHD (960x540), then the density would shoot up to ~245 ppi. AT&T doing the same would jump to ~256 ppi.
For those willing to wait, the Nexus Prime is rumored to have a 1280x720 (720p HD) resolution with a 4.65" display. That would qualify as a 'retina display' with a whopping ~377 ppi. To put that into perspective, iPhone 4 has a 960x640 resolution for a 3.5" display and ~330 ppi density (Apple's site actually lists 326 ppi since the screen size of 3.5 is probably rounded up slightly).

How can i train my cat?
Q. She is a 2 month old Russian Blue. She's now medication for an upper respiratory infection. Rather than hold her down and force the medicine in her mouth, we decided to put it on a piece of Turkey so she could take it herself. But now whenever you just so much walk in the direction of the kitchen, she runs over and meows relentlessly for any morsel of food from the fridge. The same goes for any food we bring into the house like pizza for example. She sprints onto your lap and tries to knock it to the floor. Her curiosity has given her an appetite for everything from peanut butter to mayonnaise. Please help. I would hate for these habits to follow her into adulthood or even worse, her becoming overweight and suffering complications.

---Thanks in Advance.
A. You should probably stick to forcefully medicating her. The medication isn't going to take a very very long time, so a little discomfort a couple times a day would help her to not want people food. You can also get a spray bottle and try to give her a spray of water every time she jumps on your when you have food, or jumps on the table, or when she enters the kitchen. You should also reward her with cat treats when she obeys you after you spray her. Hope I helped. :)
