First impression of the Aria is that it’s small. Small and very solid. It has the traditional build quality of an HTC handset (think Nexus One, Desire, etc.) and feels heavy in your hand. The screen itself was nice and bright in the dimly lit room, and the physical controls on the handset itself were easy to reach and responsive. HTC Aria has a 600Mhz processor, it runs Eclair and Sense very well with no real discernible lag. If AT&T decides to upgrade the OS to Froyo in the future, this thing will scream.
