Apple and Google are in a near-even race for smartphone demand, according to a new comScore study. Among those Americans looking to buy a smartphone between November and February, 20 percent are planning to get an iPhone 3G or 3GS while 17 percent plan to get some form of Android phone. Both audiences are more likely to buy a high-end device: about 14 percent of the entire group intend to buy an iPhone 3GS, while 8 percent expect to buy a Motorola Droid.
