Sony Xperia is a family of Sony smartphones and tablets. The line of phones has been manufactured since 2008, while the first tablet released under the brand was launched in 2012. The name Xperia is derived from the word "experience", and was first used in the Xperia X1 tagline, "I (Sony Ericsson) Xperia the best".
The Xperia X1 was the first phone to be released in the Xperia range. Released 2008, it featured a high resolution display (~311 ppi pixel density) and it was intended to fill the widening gap of smartphones as other competitors were producing high-end smartphone devices such as HTC and Apple. The X2 was released in the following year, which included an 8.1 MP camera and included Wifi and GPS. By this time there was a clear shift towards the smartphone end of the spectrum. An exception was the Xperia Pureness, a translucent phone without camera that was sold by selected retailers in selected cities.
The X10 was released at the start of 2010. It was the first in the Xperia line to feature the Android operating system, where previous models ran on the Windows Mobile OS. The phone was praised on its design, but its downfall was the outdated version of Android which was 1.6 at a time when competitors were on 2.1. There was a great delay in the update of the firmware, due to the heavily skinned OS, as well as Timescape and Mediascape which needed to be reprogrammed every time an update was made. The phone also lacked pinch to zoom, but this was added later as well as HD video recording. The X10 Mini and the X10 Mini Pro were, as the name suggests, miniature versions of the X10. These were welcomed with good response and proved to be very popular as there were no other smartphones on the market at that time which were as small as the two.
