This little handheld PC is a testament to just how far PDAs have come in recent years. It's got a built-in, backlit thumb keyboard for easy, intuitive text entry. With a 400MHz processor, it's speedy little device, and it comes loaded with some pretty nifty Windows® Pocket PC software (including Windows Media Player 9, for playing digital audio and video files). But here's the coolest part: it's got built-in Wi-Fi® capability, which means it can automatically connect you to wireless networks in your home, at work, or down at the local coffee shop, allowing you to browse the Internet or send and receive e-mail - a stylishly productive communications tool for the mobile professional.
Integrated WLAN 802.11b:
Enables high speed wireless access to the internet, email, corporate data and solutions such as voice over IP. WLAN and Blue tooth can also be used at the same time with no interference. Connect at the off ice, home, or WLAN hotspots (even your local coffee shop), create personal networks using peer-to-peer communication with another WLAN-enabled device for collaboration and information sharing. Includes internal antenna.
Integrated Bluetooth:
Allows wireless communication with other Bluetooth devices, lets you access the Internet or your email via a Bluetooth enabled mobile phone, and print to a Bluetooth-equipped printer. You can also exchange business cards, calendar appointments, documents, and more with other Bluetooth devices, and wirelessly synchronize data with your Bluetooth desktop or notebook PC using ActiveSync.
Enhanced security:
Grade A protection for your device, information and connection with VPN software that provides enhanced security for wireless connection, and the 64 -bit and 128-bit WEP that offers enhanced security for an authorized connection and data transfer when connected wirelessly. The F-Secure FileCrypto Data Encryption provides protection against unwanted data disclosure. There is also support for LEAP and 802.1X.
System expansion
A top-loading Secure Digital® Card slot accepts optional SD and MultiMediaCard® memory, so the sky's the limit, storage-wise. The 64MB internal memory will probably be enough for some people — however, since the RAM is used both for storage and for running programs, you'll probably want to pick up an extra memory card or two, especially if you plan to take advantage of the iPAQ's digital audio or video playback capability. The SD card slot can also handle SDIO expansion cards (think PC Cards, only smaller).
LCD
The iPAQ's 3-1/2" rectangular LCD is capable of displaying more than 65,000 colors, and it has a resolution of 240 x 320 pixels. Text is easy on the eyes, and digital photos are nice and crisp (and HP's photo-handling software looks good and lets you easily zoom in and move around within a picture). The display's backlight has adjustable brightness — you can crank it up temporarily for better visibility while you're outside in the sunlight, then dial it back when you return indoors to preserve battery life.
Connecting to a PC
HP provides a cradle with a USB connector for "synchronizing" the handheld unit with your desktop PC — a process whereby the two devices share recent data with one another in order to keep your calendar items, task lists, and e-mail "Inbox" up-to-date in both locations. This USB connection also allows you to copy specific files (music, video clips, spreadsheets, etc.) from your computer to your PDA, or vice-versa.
Other controls on the H4150 include four buttons above the mini-keyboard that provide one-button access to your calendar, contacts, and e-mail, as well as HP's own iTask app, which opens a small window in the lower right of your screen displaying all the currently running applications. It also offers quick access to system controls and brightness settings. A voice recorder button on the top left side and a 3.5 mm stereo headphone jack and a microphone pinhole and a Secure Digital card slot (which can also take Multimedia Cards) on the top.
The H4150's dock not only connects to your PC, but also charges a spare battery (available separately) while you power up your PDA. The battery is a bit larger than standard and holds a bit more charge. We got over four hours even with some wireless use. Having a spare battery would ensure that you'd be typing and tapping away for a whole work day, if you like.
