HTC has just announced the HTC One mini, a 4.3-inch version of its flagship phone. From the outside, it looks very similar to the One that HTC released earlier this year to critical acclaim. Inside, however, something had to give, and there are some notable differences. The HTC One mini has a Snapdragon 400 processor (rather than the Snapdragon 600 found in the original), 1GB of RAM (rather than the 2GB of the One), and a lower-density 4.3-inch 720p display. It does, however, feature a similar Ultrapixel camera, although the mini's doesn't have optical image stabilization. The Taiwanese manufacturer isn't the only one creating a miniature version of its product — Samsung also has a Galaxy S4 mini — so how does HTC's effort stack up?
