Check out five of the hottest tech gifts this holiday season ...

iPhone 4S

Apple's latest incarnation of the iPhone will be high on many people's wishlists this holiday season.

The iPhone 4S looks the same as the iPhone 4, but on the inside, it has a larger processor, a super-charged camera and, of course, Siri -- one of the biggest pop culture phenomenons in recent memory. The friendly voice-activated personal assistant can help users with everything from the latest weather forecast to finding a locksmith the next time you forget your keys in the car.

It's the perfect gift for everyone from your 88-year-old grandmother to your 13-year-old son, mainly because it's so easy to use.

The phone comes in black or white. A 16GB model will set you back $199, a 32GB is $299 and a new 64GB version is $399.99, all with a two-year contract from AT&T, Sprint, Verizon or regional carrier C Spire.

iPad 2

Another Apple bestseller, the iPad tablet computer was all the rage last year and its newest version, unveiled in March, is sure to be a hit this year.

The iPad is a big hit among children. It topped the list of most desired tech toys by kids and is the most-wanted tech gift this holiday season among the younger set, according to a recent survey put out by Nielson.

The iPad2 is slimmer and faster than its predecessor and includes dual cameras and FaceTime for video chat.

It's also available in black or white and comes in Wi-Fi and 3G versions on AT&T and Verizon. The Wi-Fi–only model costs $499 for 16GB, $599 for 32GB and $699 for 64GB. The pricing for the Wi-Fi + 3G models is $629 for 16GB, $729 for 32GB and $829 for 64GB.

Kindle Touch

Amazon promises an improved page-turning experience with its new Kindle Touch e-reader.

Features include an infrared display and an "X-Ray" feature, which shows you the "bones" of your book. It's also smaller and lighter than its predecessors because it lacks a physical keyboard, although added thickness prevents accidental screen touching.

Pages can now be turned with a simple touch of your fingers. No more pressing buttons.

A lighted case can also be purchased through Amazon to allow for reading in low light or darkness.

The Wi-Fi Touch is $99, and a 3G version sells for $149.
