The functionality of laptop and netbook are the same. The difference between netbook and laptop is the size.
Largest difference is the physical size and weight. Netbooks are much smaller and lighter, more portable. This is fine if all you want is to surf the web, take care of e-mails, etc. Perhaps the largest setback of a netbook is the lack of a cd/dvd drive and serial/data ports. Recently I’d purchased an Intel Atom Processor based Laptop, which allows me to access anything, anywhere and anytime and wherever I’d like to.
Intel atom based processors Netbook is a great little piece of technology, lightweight and easy to take anywhere.
