Both the Omnia and Mega are based on Windows Mobile 6.5, but the final result for each phone is distinct. And by distinct I mean the Omnia II might have the edge in the “sexiness” category. This is doubly true when you consider those screens are coupled with a large AMOLED screen. As BGR notes, however, the Mega is only a mid-range phone, and the UI could see things kicked up a bit when applied to higher end models in the future.
The Sense UI is represented here as well. Just in case you missed it, Sense is the Android interface overhaul that HTC debuted on the Hero back in June. True to their word, the UI—sorry, /”design philosophy”—is being deployed on each of its phones going forward. [ai.rs via BGR]
