I was looking forward to buy the Lenovo Miix 2 8" with 64 GB and WWAN.
But Lenovo decided that people in my market (Germany) don't need it.
So I bought a Dell Venue 8 Pro 64GB/WWAN.
To those who say that the modern UI sucks: On laptops and desktops, I absolutely agree with you. But on a device with real touch support it works, if you're willing to give it a chance. It doesn't work if you immediately start installing desktop apps.
To those that say 8" is a bad size: I disagree. In my opinion, a 10" or 11" tablet is too close to laptop size to make sense, but 8" are about half way between a 4" smartphone and a 12"/13" laptop.
