Toshiba makes a colorful entry into the netbook market with the Mini NB505 series. Featuring an Intel Atom processor, it offers a solid computing experience for a very affordable price, and its compact size and light weight make it ideal for travelers and other buyers who value portability.

With dramatic improvements in battery technology and reductions in the energy needs of modern laptops, consumers are benefiting from longer and longer battery life in laptops and notebooks. HP has recently broken a new barrier of battery life, however, by providing up to 24 hours of battery life on their HP EliteBook 6930p when equipped [...]

As laptops become more mature, the differences between models become smaller and innovations become less dramatic. One area that has seen very little change in laptops over the past decade or so is battery technology. While other aspects of the machines have been improved or revolutionized, there have been only incremental improvements in battery technology. [...]

Continuing their trend of creating some of the sharpest designs and highest-quality Windows laptops and notebooks, the Vaio X Series is no exception. The laptops are sleek and extremely thin, but still manage to provide up to 12 hours of battery life, making them an excellent choice where portability is a priority.
