For me, that piece of #OverhypedTech was the HTC One X. I loved HTC Desire, my first Android device, bought 15 years ago (!), so when I wanted to upgrade, I had no doubt in my mind that the HTC One X was the perfect fit. It had the powerful Nvidia Tegra processor, the display was crisp and bright, and the design was right up my alley.
The problem was… when I started using the device. The processor was as hot as it was powerful, and the software was very bloated. The situation was so bad I quickly upgraded to the Nexus 5.
