It seemed like a pretty safe assumption to make given the nature of the device. Google shipping a web-oriented device with non-square pixels would be very strange of them because of all the potential problems this would entail. Are there any modern portable computers with non-square pixels? For that matter, were pixel aspect ratios other than 1:1 ever prominent on LCD portables?
Last time I had to deal with non-square pixels on x86 was when programming mode 13h graphics for DOS at a 320x200 resolution (which was then stretched to 4:3). The only thing that comes to my mind that you could do now with modern equipment would be to connect your laptop/PC to a bargain bin plasma panel that has a 1024x768 physical resolution and achieves a 16:9 aspect ratio by virtue of non-square pixels [1]. My first encounter with one of those caused me trouble when I wanted to use it with a Linux PC some time ago.
