1st, let's compare the screen size. With notebook screen size normally hovers around 14.1 to 15.4 inch, you can have a good movie viewing pleasure and don't have to squint your eyes just to see some text. With screen size 12 inch and lower, you might have a hard time typing documents in your netbook.
2nd, the processor. It is a very important part or consideration because it process the website content. The faster the processor, the faster the page loads. If you normally surf around the YouTube (which is heavy in javascript and flash) then you will know that loading that website takes longer than sites such as wikipedia or forums. With a slow processor, you browser might suddenly hangs if you opened too much tabs. The netbook cpu can't even handle 1080p movie and it will shutter all the way till the end.
3rd, the graphic card. If your primary concern is playing games, you can skip the netbook altogether as their graphic are really really lame. Some claim that they install World of Warcraft inside their netbook, but with lame graphic card and small screen, how are you ever gonna enjoy playing that game. On the other hand, notebook have better graphic card than netbook even in the low-end section. They can handle World of Warcraft and other older games easily without breaking a sweat literally.
4th, the weight. This is where the netbook really shines. With their low weight (and small screen), they are truly fit the definition of portability. Thier weight are almost half of the notebook weight, which is a good thing if you're not into bodybuilding. Coupled with their power adapter, the max weight might be only 1.5kg.
พอช่วยให้ตัดสินใจได้มั้ยครับ ถ้าเน้น portability แบบเดินทางบ่อยสะดวก ไม่เน้นมัลติมีเดีย เล่นเกมส์ ดูหนัง มากนัก ก็ Netbook เถอะ ผมยังอยากได้ซักตัวเลย
