Netbooks and notebooks have some key differences. Notebooks typically have more powerful dual-core processors, larger hard drives up to 320GB, DVD/CD drives, can run software like Photoshop and Microsoft Office, have larger 6-9 cell batteries, and weigh more. In contrast, netbooks have less powerful Intel Atom processors, smaller hard drives up to 80GB, no disc drives, cannot run heavyweight software, have smaller 3-6 cell batteries, and are smaller and lighter than notebooks.
