What is the cheapest place to get a Dell netbook?

Dell Netbooks are wildly popular, and fun! The cheapest price I found was at http://www.amazon.com for $149.99 (a STEAL!), but I have also included some others close in price, for comparison purposes. I have also included a carrying case, as it is always important to protect our computers. This is the product info. on the Netbook for $149.99:

Product description: Personal computing just got a whole lot smaller with the slender Dell Inspirion Mini 10 netbook, which includes built-in AT&T 3G wireless capabilities as well as unlimited access to AT&T Wi-Fi hotspots. A larger sibling to Dell's Inspiron Mini 9, the Inspiron Mini 10 adds keyboard comfort and even more entertainment-friendly dimensions to the Inspiron Mini family. Like the Inspiron Mini 9 and Mini 12, the Mini 10 is a compact, easy-to-carry Internet companion that's ideal for teens, tweens, travelers and "Tweeters" to surf the Web, chat with friends (both via text and using the integrated 1.3-megapixel webcam), stream video and audio content, and upload on-the-go photos to blogs or social networking sites. Standard built-in Wi-Fi means quick and easy wireless internet access to hotspots in the home, on campus, in a local coffee shop, in the office or at a conference. The Inspiron Mini 10 features an intuitive Dell-developed custom home screen interface that is designed to make it easy to find what you're looking for. Intuitive icons link directly to groups of similar applications, like games, Web and entertainment, and favorite web links for quick access. Plus, the home screen can be personalized, putting your favorites front and center. A bright 10.1-inch display is designed to be able to present web sites without a lot of left-right scrolling, and the 92-percent full-size keyboard is large and easy to navigate. An HDMI port also allows you to connect the Mini 10 to your HDTV for large-screen, high-def viewing. It's powered by the 1.33 GHz Intel Atom Z520 processor, which is designed especially for mobile devices and features an innovative hafnium-infused circuitry that reduces electrical current leakage in transistors to conserve energy. Other features include a 160 GB hard drive, 1 GB of RAM (533 MHz; maximum capacity), integrated Wi-Fi connectivity, three USB ports, 3-in-1 memory card reader, and a 6-cell battery with up to 6 hours of battery life. It comes preinstalled with the Microsoft Windows XP Home operating system, which offers more experienced users an enhanced and innovative experience that incorporates Windows Live features like Windows Live Messenger for instant messaging and Windows Live Mail for consolidated email accounts on your desktop. This netbook also includes Microsoft Works for creating and editing documents and spreadsheets. Enjoy and thank you for using IMShopping!
