The 15" SB looks like a stellar machine, but given MS's non-worldwide support and the history of variable reliability of the Surface line, it doesn't look like a good idea to import it when you don't live in the US, the only country where it's currently available.

No. The links you provide are for the 13.5", notice they all specify a 1050 and make no mention of a 15" option unlike the US store[0].
The article and my comment are about the 15" machine, which is literally only available on the US storefront (not even the Canadian one[1]) with no word whatsoever that I could find (so far) as to its eventual availability outside the US.
