The DM3T is based on a low voltage Intel processor, has a very bright 13.3 inch screen, a comfy keyboard with island-style keys, a full compliment of expansion ports. and a six-cell power pack that delivers some of best entry-level portable battery life I’ve ever seen in years. The unit supplied to me for this review included 4 GB of memory, a 1.33 GHz dual core Intel Pentium ultra low voltage Intel Pentium processor, a 320GB hard disk drive, 13.3-inch LCD screen, Microsoft Windows 7, antivirus and HP digital multimedia content management plus integrated camera with digital microphone. The price as configured is $549. The DM3T surprised me with its functionality, extraordinarily long battery life and rugged construction. In three charge cycles of real world usage-- including one arduous flight, this notebook’s six-cell power pack gave me better than 6.5 hours of untethered juice. And that was with a power scheme that didn’t cut my consumption very much. Consider me impressed. The overall usability and suitability-to-task of HP’s Pavilion DM3T is excellent. It’s 13.3-inch screen is bright enough for me to read the fine detail of quarter sectional maps of California’s Gold regions without the eyestrain you’d expect for a user past middle age. Furthermore, the integrated graphics controller had the power to make my detailed tabular data readable. The integrated 802.11 n wireless network adapter works as well in my home office as it did seated outside a Starbucks up in the California Gold Country keeping me attached to the Google mother ship where my personal productivity apps lives. And it stayed attached, despite at least nine haughty IPad users greedily sucking bandwidth and their double espressos made with some sort of dubious milk product food froth. The HP PavilionDM3T has a big voice for an ultra light portable. Its integrated Altec Lansing speakers and Dolby audio subsystems pump out crisp clean music. I also like the position of the external expansion ports which are easily accessed without resorting to acrobatics or extreme yoga. The 5-in-one media reader included on the DM3T willl make any digital motion or still camera user very happy. But what really surprised me about the Hewlett Packard’s DMT3 ultra lightweight notebook -- which weighs in at a skosh under four pounds-- is its rock bottom price---$549. The only option I strongly recommend is the $25 back lit keyboard, a feature I really appreciated testing this machine while car camping 10 miles from a major road. Go ahead and splurge on the backlit keyboard. Its worth it. I was very impressed with this notebook’s capabilities, its well above average construction and it’s svelte profile. HP has paid a lot of attention to thermal management in this notebook. Embedded sensors kick this portable’s cooling system into overdrive if heat builds up. It’s a nice engineering design feature I think will yield increased system life and I hope the technology spreads to other HP portables. One word of caution: the HP DM3T does not have an integrated optical drive, so if you need to load software from a CD, you’ll need to get your hands on an external drive. In total, I think HP’s DM3T is one of the most outstanding machines I’ve reviewed in a long time. So it’s time to haul out the marble pedestal, unlimber my sculpting tools and install this skinny powerhouse in my pantheon of portables where it joins another landmark family from an earlier HP era, the HP OmniBook 300-800 line. I like and recommend this portable a lot--Jim Forbes on 04/05/2011. Sometimes I test a new notebook that resets nearly all of my expectations for portables or which reaffirms my beliefs in a manufacturers. Hewlett Packard’s pavilion DM3T fit’s this description exactly.
