iPhone 4S Launches Today: Top 10 Reasons Why Apple's New iPhone is Worth Buying (PHOTOS)

iPhone 4S Already Has Record Pre-Order Sales

One million iPhone 4S devices were sold in the first 24 hours of pre-sale orders, compared with 600,000 iPhone 4s in 2010. That makes iPhone 4S Apple's best product launch ever.

When iPhone 4S hits the shelves later this morning, buyers can look forward to Siri, the intelligent voice recognition software that looks to be iPhone 4S's crowning glory. Additionally, iPhone 4S boasts a faster processor, improved camera and battery life, all new apps and full Twitter integration.

Apple founder and iPhone inventor Steve Jobs died Oct. 5 only one day after iPhone 4S launched, and that may have inadvertently spurred more sales. Despite the fact that Samsung, arguably Apple's number one competitor, has multiple lawsuits pending against them, Samsung even delayed announcing their new smartphone this week in honor of Jobs.

It was a classy move, but one that might not win Samsung enough support to become the top smartphone maker, as the iPhone 4S pre-order numbers indicate. iPhone 4S ships today and the wait is over. Many were hoping for a totally redesigned iPhone 5 with a larger display, but instead got the better-on-the-inside iPhone 4S. Start the slideshow to check out the top 10 reasons why iPhone 4S is worth buying.

Let us know in the comments if you think iPhone 4S is a winner or if Apple is now a year behind Android smartphones.
