I received my Cube i7 Stylus two days ago. Similarly, the box was unsealed and there were scratches on the first layer of the screen protector. That didn’t bother me that much, especially since I replaced the plastic screen protector with tempered glass (Surface Pro 2 glass fits, except for the camera cutout). The cracked version of Windows 10 was awful! None of the W10 Apps worked – all would crash with a “Your Trial Period For This App Has Expired” error. I also had SSL cert errors.
I used a legit W10 key to reinstall and everything’s been great since. You can definitely tell the difference between a Core M with an SSD and an Atom chipset with EMMC. The i7 Stylus blows my old TW802 Winbook out of the water.
