We have known for a while that dual-core netbooks are on their way. ASUS and Acer have already announced their new netbook models, taking advantage of dual-core processors. HP is expected to join them soon. HP Mini 5103 is a brand new, dual-core machine that is 20% faster than its predecessors and will offer up to 11 hours of battery life. This netbook is expected to offer better graphics capablity and can play back 720p videos.

Mini 5103 is a high-end netbook, which means you get a fast hard drive, optional broadband and GPS capability, and a decent spill-resistant keyboard with it. The device is expected to ship for $399. It is slated to start shipping on September 17th. These dual-core models may be a tad bit more expensive, but they can handle those complex computing tasks much better.
