Wow I've been feeling this exactly but never had such a good description. Great interview, thanks for posting.
My ideal machine would be something along the lines of - fanless Intel CPU, 14" 1080p or better IPS display, excellent backlit keyboard with TrackPoint, 12+ hour battery life for 60% screen brightness and wifi, 3+ USB ports, 512+GB fastest local storage possible (so PCIe x4/M.2 or something). I don't care for anything else although I would take an HDMI or DP out and Bluetooth if possible :)
(I'd rather disable the fan in software so I could turn it on as needed but have not gotten that to work.)
I could probably get fiber to the house here now, but running the gear would use more than my total current power budget. Also, I kind of like a more measured pace in the webpages I read.
I think DSL still isn't an option, so LTE is probably the best choice there at this point (it isn't super isolated, there just aren't enough people on the road to bother putting in a close enough box).
