I like 9:16 aspect ratio displays on smartphones which is the aspect ratio of FWVGA, qHD, HD and Full HD displays. Apple adopted the a 9:16 for the Apple iPhone 5. This aspect ratio is ideal for watching HD and Full HD video, and makes for narrower and handier large screen phones. It is fine for use browsing mobile sites. I think it is a great aspect ratio for a device used mainly on portrait mode, and less frequently on landscape mode.
With tablets, it is a different story. I prefer devices with a 3:4 aspect ratio like Apple iPad's. While most Android tablets use the 9:16 aspect ratio, there are a growing number of Android tablet using 3:4 aspect ratio displays like the 8-inch Cherry Mobile Fusion Wind and the soon to be released Acer Iconia A1.
Another contender in this Arena is the KATA T2.
- Android 4.1.1 Jelly Bean
- 8-inch XGA (1024 x 786) IPS display
- 8 GB internal storage expandable via a MicroSD card slot
- 1 GB RAM
- 1.6 GHz dual core processor
- Mali-400MP graphics
- 5 MP primary camera
- 2 MP front camera
- 4100 mAh battery
Compared to the Cherry Mobile Fusion Wind, the KATA T2 is priced 1K higher. For this you do get more internal storage (8 GB versus 4 GB) and better camera (5 MP primary and 2 MP front versus 2 MP primary and VGA front). You also get bluetooth 2.1, which alone, in my opinion, is worth the 1K price difference.
