Motorola brought back the popular Razr name for its latest smartphone offering Oct. 18, and at $299, the new Droid Razr has but one goal in mind - Challenge the iPhone 4S for smartphone supremacy.

iPhone 4S already sold four million devices in only its first three days of launch. Those numbers may have been bolstered by Steve Jobs having died only the day after iPhone 4S was unveiled, but they are enormous numbers, nevertheless. Droid Razr hits the shelves Nov. 6. so not all of its capabilities are known yet, and obviously we can't compare the sales numbers yet, but the specs we do know make for a compelling comparison.

On the question of battery life alone, a topic Apple products do fairly well with, Razr looks to have the edge. But, the 12.5 hours of talk time Motorola boasted at the launch is at 3G speeds. The Verizon LTE network is capable of power hungry 4G speeds, and the number could easily be cut in half, giving iPhone the edge.

Some of the other numbers also make a compelling case for Razr to be the premier smartphone available in the U.S. However, the most obvious number is the price. iPhone 4S can be had for $199, while the Razr is $100 more at $299. It's true that Razr has more storage, 32G compared to 16GB, but that's plenty of space for most users. The $100 difference in price will jump out more to people than the sometimes confusing storage numbers.

After the price, the main difference between Droid Razr and iPhone 4S is the screen size. Razr has quite a bit larger of a screen, but after that, some of the specs are pretty similar. Here's a side-by-side comparison:
