The Gram line of laptops is one of the best in the business. The Ultra PC 17 and Ultra PC 16 are both lighter and cheaper than the previous models. The models are available for a starting price of over $1,000.
Mirametrix is a software that is more common to see on high-end laptops. The program uses a device's camera to see where a user is. When you step away, the screen can be locked. If it sees someone peering over your shoulder, it can make the screen blurry. If you have an external display connected, it will move your window to whichever screen you are looking at.
It works well when I use it on other laptops, and is easy to turn off if you don't want to use it.
The 17-incher is 4.37 pounds heavier than the 16-incher. Both Grams are under three pounds. Grams are some of the lightest laptops on the market, and the Ultra PC models are not very heavy. The 17-incher can be used for more intense graphic tasks than the 17-inch Gram can handle.
You have a choice of processor types. The 17-incher is powered by a 12th Gen Core i7 chip, while the 16-incher does not.
