The Asus 1201PN looks very similar to the amazingly popular Asus 1201N, but has been updated with the latest ION 2 graphics card. As one can observe, Asus has added a letter P to its name which is used to refer to the Atom N450 processor that powers this netbook. Also, the Atom N330 has been replaced by much more power-frugal Intel Atom N450.
Reviewers all over the Internet have criticized the Asus Eee 1201N for its poor battery life due to its dual-core Atom processor coupled with the HD graphics. This used to turn off a lot of users because they always had to lug around the heavy power adapter. The Nvidia ION 2 take care of this problem and they are not slower than the latter. All this combines to give you much better battery life and satisfactory performance.
The Asus Eee 1201PN can easily output 1080p HD videos. But, gaming on the Eee 1201PN is a mixed bag. If you planning to play games like Warcraft and Battlefield heroes, then you would not face any problems. However, if you have plans to play Anno 1404 or similar games, then you are going to be disappointed as they would run like slideshow.
Coming to its battery life, you will get somewhere around 3-5.5 hours of runtime, depending upon the usage. If you are doing only web-surfing on the computer via Wireless LAN, then expect over five hours of runtime, but if you are one of those people who like to push the netbook to its limits, then the runtime fall back to 3 hours which is still much better than the Asus 1201N, which has a battery life of under 3 hours.
