Windows tablets with 3G/4G/LTE

A friend of mine asked me about a good Windows (8 / RT) tablet with built-in 3G/4G/LTE connectivity (must-have feature for him). And when I tried to recall few names of current-gen (and previous-gen) devices it struck me that the choice is VERY limited.

I can recall:

  • Asus Vivoatb Smart
  • Lenovo Miix 10
  • Asus Vivotab RT (withdrawn)
  • Samsung Smart PC (VERY expensive in my country /?!/)
  • Nokia Lumia 2520 (expensive nad not available in my country)

Almost all these tablets are previous-gen products with Atom Z2??? or Tegra 3. Am I missing something? Is there any 8 or 10-inch Windows tablet with 3G or 4G connectivity?

I know I should wait for Miix 2 10 or Thinkpad 8, but it will probably be quite expensive in the first months and be available in my country much later than in US.

Any suggestions, guys?

PS: He doesn't want neither iOS nor Android device .
