The device has a standard memory slot (such as an SD or micro SD card slot) so that you can either extend the internal storage with affordable memory modules or you can retrieve data, such as photographs, easily from a memory card.
IPS (In-Plane Switching) is a technology used for LCDs. It was designed to overcome the main limitations of normal TFTs TN-matrices: relatively slow response times, small viewing angles and low quality color reproduction.
The device has a display with three full subpixels per pixel, resulting in a sharp and crisp picture. Pixels in some displays (like AMOLED) share one subpixel to preserve space. This can result in a less crisp, slightly blurred image.
