Over at SiliconValley.com, Dean Takahashi points out that GPS devices topped electronic sales on Black Friday, the big shopping day after Thanksgiving:

Two years ago, the devices that get their location fixes from global positioning system (GPS) satellites cost $1,000. But the cheapest ones now have broken the $100 barrier and many are now competing on a variety of features. GPS devices were the No. 1 electronic purchase on Black Friday, up sixfold over last year in unit sales. The average price was $189.

Another indicator of how useful people find location info, and another point underscoring Nokia’s logic of incorporating GPS into the Nokia N810 Internet Tablet.
