For most people, a smartphone isn't on the top their list of things to get that special someone this holiday season. A recent survey by research firm InsightExpress indicates, however, that a smartphone with integrated phone, e-mail, personal data, Internet, multimedia, etc. is exactly what a quarter of Americans really want.

Bellow is a list of several of the hottest smartphones currently available. With one of these 'stocking stuffers,' you'll be sure to stay connected to your loved one in a myriad of ways.

Young & Hip

T-Mobile Sidekick II (also known as the Danger Hiptop2)
This handset is the ultimate smartphone for teens and people in their early 20s. Everything about the Sidekick II says it's the phone for kicking back, and it's hard not to fall under its spell while playing with it. Shortcomings are obvious—no Bluetooth or expansion card slot—but it isn't meant for business use, anyway. What it does have are several ways to stay in touch with your friends and a colorful, cool interface.

The suggested price for the Sidekick II is $299, but with rebates it's easy to find for $199 with a new T-Mobile account. For the best deal, though, surf to Amazon.com, which is giving it away for free with a new T-Mobile account. It's an amazing offer for such a good phone.

Money No Object

Hewlett-Packard iPAQ h6315
The Hewlett-Packard iPAQ h6315 from T-Mobile is an international quad-band GSM/GPRS Pocket PC Phone with built-in Wi-Fi for linking to wireless LANs and hotspots, and Bluetooth for connecting to a wireless headset or sending documents to a Bluetooth-equipped printer. It also features excellent audio and visual functions with a built-in camera, as well many of the characteristics that have helped make HP the best-selling Pocket PC vendor.

Cingular Siemens SX66
This Cingular Wireless Pocket PC Phone implements a traditional tablet (and rather large) design like the h6315. You also get Bluetooth and Wi-Fi like the HP. Unlike the HP smartphone; however, it doesn't integrate a camera. But the SX66 does implement a retractable thumb-keyboard for easy messaging and data entry. (The HP bundles a keyboard accessory.) It also has a faster processor and more memory (128MB to 64MB) than the h6315.

Both Pocket PC Phones go for between $500 and $600, depending on service contract.

Sprint supports a CDMA Pocket PC Phone (the PPC-6601) built from the same design as Cingular's SX66—OEM HTC's XDA III. Unlike the SX66, the PPC-6601 doesn't integrate Wi-Fi.

Phone-Like Smartphones

Three smartphones, the palmOne Treo 650, Research In Motion BlackBerry 7100, and Sierra WirelessVoq Professional Phone implement keyboards in handsets that are still compact enough to handle like standard mobile phones rather than PDAs that add cellular functionality.

palmOneTreo 650
Even though palmOne's Treo 600 is one of the most popular and best-reviewed smartphones around, it is—at over a year old—getting a little long in the tooth. Enter the Treo 650 with an improved keyboard, a high-resolution screen, Bluetooth, removable battery, and compatibility with palmOne's Wi-Fi SD card. Like the Treo 600, the Treo 650 integrates a VGA, but improved, camera and 32MB of RAM.

Available exclusively from Sprint ($499 without service contract) until the end of the year on its CDMA network, expect to see GSM editions of the Treo 650 coming from other carriers, like Cingular, sometime early next year. You should also look for good deals on the Treo 600, which, even though it is a year old, is still better than many newer smartphones on the market.

RIM BlackBerry 7100
Shipping from T-Mobile in the United States as the BlackBerry 7100t, RIM's first smartphone for consumers nixes BlackBerry's signature keyboard and boxy design for something decidedly sleeker. As with other BlackBerries, the 7100t delivers e-mail, instant messaging, HTML Web browsing and organizer capabilities. It does this, however, in form factor that is more like a traditional, and slim, mobile handset.

With the 7100t, RIM replaced the BlackBerry thumb-keyboard with one that uniquely merges a keypad and a keyboard. For text entry, each key supports two letters, while predictive text software called SureType helps you accurately input text-so when you press a key the 7100t knows which of the two supported letters you mean to use. It also supports Bluetooth.

The 7100t sells for $200 after mail in rebates.

Voq Professional Phone
Perhaps the most unique feature of the Voq Professional Phone—based on the Windows Mobile for Smartphone platform—is its QWERTY thumb-keyboard, which, unlike other smartphones, implements a standard phone keypad that flips open to reveal a thumb-keyboard. As a result, the keyboard is larger than what you would normally find in a smartphone. It also lets Voq maintain its svelte 5.2 x 2.09 0.9 inch dimensions.

Other Voq features include a 2.2-inch display that supports over 64,000 colors and a 220 x 176 pixel resolution. There is also a speakerphone, a Secure Digital slot for memory expansion, 32MB of ROM, 32MB of RAM, and a 4-way joystick controller. You can also listen to music on the device.

Voq sells for between $500 and $600. AT&T Wireless supports Voq in the U.S.
