I've played it naively on my windows tablet (requires an intel processor) both running windows 8.1 and now windows 10. works fine. there are NO phones YET running windows 10 with intel processors. there are several in the works, but none can be released until microsoft officialy rolls out windows 10 for phones. I have also used remote desktop to connect to my home computer while it's running nwn. remote desktop is slow, expect anywhere from 1-5 seconds of lagtime, depending on your connection. (poor cell signal could even be worse than 5 seconds of lag time, and just disconnect you randomly)
An example of this is the Elephone Vowney (model B) right now, the chinese phone manufacturer Elephone is releasing their new flagship the Vowney. they plan on releasing 3 total models. the Vowney, the Vowney Lite, and the Vowney Model B. they currently have "leaked" info on the windows/android intel CPU based dual boot model B. but no hard info yet. so anyone paying attention is excited about the model b, yet all you could preorder right now is the regular vowney, and the lite, both of which have ARM processors, NOT intel. (release date october 10th on those two) Since the mediatek CPU the first two models are using WOULDNT RUN NWN, it's useless. wait a month or two, and odds are good that the intel based with windows/android dual boot will be unveiled and there will be hard evidence as to specs. it wouldn't be released in america, ever, so if you are in the U.S.A. you would need to buy one from china, ship it to you, then go with AT&T, or T-mobile (or one of their many many MVNOs like straight talk or net 10 etc) to even service one after buying. As for data speeds, at least 3G possibly but less likely 4G, since official specs aren't even out for this model yet. 3g is enough to pvp with nwn, but is a mediocre connection, playable, but not the best.
Right now, this is the closest to production of ANY phone that will be able to natively run nwn. there are plenty of phones with android and an intel processer (Asus Zenfone 2 for instance), but without a working copy of windows 10 for them, they cant run nwn natively. and there are plenty of windows phones with an ARM processor (Lumia series comes to mind) but you need both the operating system AND the CPU to make it work. If a phones processor is listed as something like MTK6795 or snapdragon 810, or whatever, it doesn't matter how powerful the phone is, it just wont run code like NWN that is specifically designed for the intel (x86 and x64) processors. and since AMD isnt making phone CPU chips yet, your only option for the critically important x86 architecture is Intel (and x86, x64 is all intel makes, so you know if its got an intel chip and windows, it's compatible) Technically an ubuntu phone with an intel processor would also work, but none are close to completion right now. the only two ubuntu phones I know of are running ARM chipsets.
