The editors of Entrepreneur.com sifted through hundreds of inventions that became available within the past year to compile a diverse list of innovative, practical and fun products.

1. iPhone - which consumers camped out for prior to its June debut, is the obvious choice for any “Best of 2007″ list. Much more than a phone, it also features an iPod, a camera and the internet, all in one. The multi-touch display allows you to control everything with your fingertips. Zoom in and zoom out on maps to determine your driving route and use the Visual Voicemail to listen to your messages in any order you choose.
2. Kindle - Since it became available in November, Amazon.com has struggled to keep this new electronic reading device in stock. The revolutionary portable reader downloads books, blogs, magazines and newspapers. The Kindle features a high-resolution electronic paper display that looks like real paper. Readers can choose from more than 90,000 books available in the Kindle store, including new releases and New York Times bestsellers. Aside from the cost of books, which run around $9.99, there are no monthly wireless bills or service commitments.
3. ZPrinter 450 - This device can transform electronic 3D data into colorful, handheld physical models. It can be used to create architectural concepts, landscapes, engineering product designs, electronic entertainment objects and medical information. The ZPrinter 450 is the third 3D printer made by Z Corp. and is touted as the most compatible with contemporary office environments. The ZPrinter 450 breaks down 3D printing into seven easy steps. It also includes automatic setup, power loading and self-monitoring of materials and print status.
4. iRobot Looj Gutter Cleaning Robot - iRobot, maker of the Roomba, says it’s the first product designed to make gutter cleaning faster, easier and safer. The robot is controlled by a wireless remote that’s also a detachable handle. The Looj can clean a 60-foot section of gutter in just 10 minutes. It drives under gutter straps while dislodging and eliminating dirt, leaves and debris. The robot works with standard K-style, aluminum, copper, metal or vinyl gutters.
5. QwikGrip - After eight years of development, inventor Leonard Duffy has created the Velcro of the future–a fastening technology that snaps into place and slides into full engagement. His “slidingly engaging” systems are applicable to many industries, including apparel, sports, health care, safety and military. Duffy says his invention can bind a new plastic cast or even take the place of shoe laces. Right now, the fastening technology is on the market as a business-to-business licensing opportunity, though it’ll be available for consumer purchase in 2008.
6. GreenSwitch - Originally, the GreenSwitch system was designed for controlling energy use in hospitals and hotels. After reducing energy costs by 25 to 45 percent in those industries, the technology has now entered the consumer market. The wireless system can reduce home energy consumption by turning off all designated light switches, wall plugs and air conditioning with the flip of a switch. After flipping the switch back on, all plugs and systems return to normal modes. The system can be retrofitted in an existing home or added to a new home during construction.
