Don't know if it helps, but I carry a small laptop with a wireless connection when on the road and it works well, not that I use it often but when something changes drastically in Tcond. or scratching it comes handy.

They are cheap as chips these days and you need less then a Gb limit, I make do comfortably with 600 Mb but don't use it every day.

Good luck.

Ps when not at home and running a bot you need a UPS as well, in case of power failure!
