“Totally worth every Penny”

I can say that the Xiaomi Mi Air 12 offers the best feature to price ratio currently available. If you are looking for a premium laptop, then this is it. Even though, it is a bit pricy, it does offer plenty of awesome features on the side. Aside from the premium body, it also has one of the best Keyboard and Touch pads of any notebook I have tested. Also you have the High Grade AKG speakers.

“The most affordable Core M Ultrabook”

The Cube i7 Book isn’t the best looking out of the three, but it certainly is the most affordable. Sitting at $300, it offers 100% Guaranteed Performance all the time. The build quality is also quite good and the Wacom stylus support is also a big advantage.

“Great looking Surface Pro Lookalike”

The Cube i9 has some weird issues, nevertheless it does look good. It also offers solid performance and runs a few degrees cooler than the Cube i7 Book
