Dell Inspiron Duo review:

Dell Inspiron Duo

Those looking for the kind of instant-gratification tactile feedback provided by the iPad shouldn't get their hopes up. Tablets need either much more powerful components, or operating systems designed for their hardware, instead of touch interfaces slapped over Windows 7.

Any Netbook worth a look should run 4 or more hours on a single charge; after all, these portable systems are designed to travel with you all day, and use very low-power components. However, in our video playback battery drain test, the Dell Inspiron Duo ran for only 2 hours and 18 minutes. Even making allowances for the power overhead the touch screen requires, that's not nearly long enough for a 10-inch laptop.

Dell includes a very basic one-year warranty with the Inspiron Duo. Adding in-home service costs $50, and expanding that in-home service plan to three years is $239 (or for $250, you can include accidental damage protection). Dell's Web-based tech support sections are generally easy to find and well-organized, with driver updates, FAQS, and online chat.
