As smartphone enthusiasts, we like to see big improvements from one generation of phones to another. HTC’s current flagship, the Desire HD, is no slouch: it’s powerful (with a single-core Qualcomm Snapdragon 1GHz CPU and 768MB of RAM), it feels high quality thanks to its unibody construction, and it’s slim (at 11.6mm) and pretty light weight (at 5.78 ounces). But the new flagship from HTC, the HTC Sensation, is not only more powerful (with a dual-core 1.2GHz Qualcomm Snapdragon and 768MB of RAM) with a higher resolution screen, but it’s thinner (at 11.3mm) AND lighter (at 5.22 ounces). Very impressive!
