HP Folio 9470m

1. Extensible external battery, and enough standby time 2. It is strong and can really stand alone 3. It is easy to expand and maintain. It is basically as long as a few screws are removed, and many screws have springs and clips, which is very practical 4. Dual channel+Ultrabook+VGA+DP, it seems that there is no second model on the market 5. The metal shell is not unusual. What's interesting is that there is a rubber like coating on the surface of the machine. Although the existence of this coating makes the product become a fingerprint collector, the feel is really better

1. Without a good screen, the screen size of this machine is different from that of the normal 14 inch, and the display effects of the 768P and 900P are really terrible. I feel I have bought more than 3000 low-end machines... After color calibration, it is much better, but only if you have a color calibrator or someone "accidentally" has given you color calibration documents 2. The touchpad can't use the "momentum" function in the driver very well. It is suspected that the firmware is too old, which I think is somewhat inconceivable 3. Only the SSD version does not have a 2.5sata shelf... one shelf is 300 oceans... and it is only compatible with a 7mm hard disk 4. The screen axis is not well done. There is no business model of 180 degree rotating screen axis. Of course, the tn screen, 180 degree, I think, can't be used

This machine has overturned my understanding of the Ultrabook, but... generally speaking, I feel that there is still room for improvement... and this book is said to be a Ultrabook, thin... But it is really not light, especially with batteries, which are all aluminum alloy shells, still very heavy
