Back in 1999 to 2001 I traveled a lot for the company I worked for, mostly visiting military units/bases within North America with some European trips abroad as well. This was before the advent of wifi everywhere, and my Toshiba Notebook which was top of the line at that time of course didn't have much in the way of a gaming video card, so I COULD play, sort of, but it was all dial up connection from the hotel, which wasn't cheap, although my company paid for my "roaming" account as it was called back then, the rates were more ridiculous than early warbirds/hour rates. Amazing that only 10 years later, there was hi speed wifi in nearly every hotel and more, and home connections even without FIOS or fiber to the curb can be had up to 250mbits, which is what I'm using at home now for under 80$ a month.
If I was back on the road a lot now, I'd be a lot happier playing, as even a 1000$ laptop can be had with an SSD and a top of the food chain GTX 770 or 780 video card, and with pretty decent wifi connections, the OP's insane net status not included of course, it would be better than being at home for a lot of people. If someone would just make a mini-hotas for traveling now...
