PREVIEWED - Garmin's impressive new nuvi 3790T

"The Garmin nuvi 3790T is a very impressive device, because of its
sleek hardware that's already earned it the "The Blade" nickname, but
also because of it's sheer responsiveness unseen on a GPS unit so far.
To navigate the menus but particularly for the map display while
navigating or scrolling the map in exploring mode with "pinching" and
"expanding"...and the software isn't even final..and this is with a
screen resolution that's been bumped up 3x from 480x272 to 800x480.
Speed issues had become a problem on Garmin GPS systems since the 765
and recent TomTom GPS systems have them to (x40, x50 and even the new
GO 1000 whose software isn't final either)). There are exciting new
features as well (terrain rendering, stealth voice control, nuRoute,
etc...) so these excellent first impressions will now have to be
confirmed on the road, sometime in early June hopefully!"
