2009 was chock-full of new trends and innovations. The relentless march of new technologies brought about more powerful devices in smaller packages, enabling such new devices as advanced smartphones, more e-book designs, and powerful lightweight netbooks.

Let's take a quick review of some of this year's best new products. Leave a comment below on what you think the best product or trend was, in 250 words or fewer, and the best response will win a free year of our growth-oriented Rule Breakers newsletter!

Smartphones: The year saw numerous new models that kept this growing field as competitive as ever. Palm started out the year by announcing its sleek Pre phone, which featured a slick interface that allowed easy multitasking between applications. At the tail end of the year, Motorola (NYSE:MOT) released its Droid phone to rave reviews. Of course, you couldn't forget about Apple's (NASDAQ:AAPL) most recent revamp of its iPhone, which featured a big bump in processor speed that promises to make the phone a more serious force in mobile gaming.

E-readers: The reigning king of e-books, Amazon.com (NASDAQ:AMZN), released a new generation of Kindles. However, several competitors served notice that Amazon won't control this market without a fight. Sony and Barnes & Noble released competing offerings, while several small, private companies, like Plastic Logic and iRex, also announced ambitions in this growing segment.

Netbooks: The year saw several advancements in netbooks. In addition to new netbooks from the usual players, like Dell (NASDAQ:DELL), Hewlett-Packard, and Asian manufacturers like Asus, Nokia jumped into the segment. However, netbook news wasn't limited to hardware advancements. Google (NASDAQ:GOOG) announced a new operating system that's tailored to run on netbooks. Its Chrome OS will require fewer resources, focusing the computer instead on running through a Web browser.

All the products above might foreshadow a larger trend toward more lightweight, Internet-connected consumer devices that bridge the gap between products listed above. Qualcomm (NASDAQ:QCOM) certainly believes this; it recently announced a new product that will function in a space between netbooks and smartphones. Apple's rumored tablet or Microsoft's (NASDAQ:MSFT) Courier concept also look to test consumer demand for this niche. And we haven't even mentioned innovative trends in energy or health care -- such as online medical records.
