So I thought I'd give Nokia maps a try: map the route from my house in Ohio to my daughter's in Utah, 1820 miles, all but 6 on interstate highways. Google maps gave a good answer in under 5 seconds. Nokia maps, although it found the addresses quite quickly, still is wheezing and puffing after about 15 minutes and has not returned anything useful. To be fair, Bing maps, which I understand use Nokia's mapping, returned driving instructions about as fast as google, and nearly as good.
The satellite view from Google also was better than Nokia in both size and resolution, and better than Bing in size.
I'll stay with Google for a while, thanks.
