iPhone 4S sold four million devices in its opening weekend, but that doesn't mean any of the Android phone makers will be running scared because of those gaudy numbers.

It's true that Reuters did an informal survey that said people would switch to iPhone, but Apple owns the high end smartphone market only.

Some reasons why all those Android users might want to switch could be iPhone 4S' faster processor, eight megapixel camera, voice recognition and 4G capability. It's true there are many different Android capable phones out there now. But, the most basic thing that people understand and in fact operate with smartphones is the operating system itself. If Android can't win with better handsets, like the Nexus Prime, then the system will have to duke it out with iOS 5.

Obviously, there hasn't been the fever pitch of hype surrounding the Nexus Prime as there is for any Apple product, but perhaps there should be. Google is widely believed to be unveiling their latest update to Android, the new version being called Ice Cream Sandwich. It's a mashup of Android 2.3 and Android 3.2, and it's a new operating system meant for both tablets and smartphones. Nexus Prime could be the device it debuts on, so iPhone 4S would have a legitimate contender, what with Prime bringing new software and hardware advancements.

The specs are not known for Nexus Prime, but it's believed to be readying a curved screen, thin profile, a 1.5 GHz dual core processor, 1GB of RAM and a 4.65-inch 720p Super AMOLED HD display for the Oct. 19 launch. It wil have to be an impressive system because Siri and iOS 5 are proving to be top notch additions to iPhone 4S.

Tell us in the comments if you think Nexus Prime could be the best selling smartphone this shopping season.
