If you were paying attention during HTC’s keynote earlier this morning, you’ll have noted Peter Chou dropped a big old promise on us all: no more waiting for maps to load when zooming or scrolling. Pre-cached maps are one of the headline new features in the upgraded Sense that accompanies the Desire HD and Desire Z ‘s announcement today, so we naturally had to go have a peek for ourselves. Requiring no internet connection, the Desire HD on hand sauntered through the streets of Sao Paulo and it was true that there were none of the aggravating grey squares of doom that we’ve grown used to when panning around.
