I do pretty well with my older DELL M90 Workstation setup running XP PRO.
I guess this coming year MS will stop sending out updates for the XP system so will probably have to update my operating system. I am going to go for just Windows 7..
My setup on the road is almost 99% the same as it is at home. I use the same M90 laptop sitting in a DELL DOCKING station with external monitors, keyboard, sound, external I/O items. I just grab the M90 LAPTOP from the house and move it to the trailer and drop it into the DELL Docking station. I also have several USB hard drives with all my special projects data stored like photos and my two-way emergency radio OPS I like to do...
We use VERIZON MIFI for internet connections across the country. Right now I get away with a 3GB DATAPLAN but will probably go for the MILLENICOM MIFI based setup 20GB dataplan setup in the near future.
We use the NATL BROADCAST system for TV using the BATWING antenna and occasionally downstream a missed HDTV program using free 'WATCH TV-SERIES' internet TV program. Used to bring along the SAT TV stuff from the house but the quality of the NATL BROADCAST free to public system turned out so good for us we stopped bringing along the SAT items.
I got my M90 DELL workhorse laptops from off-lease sales on the internet. You can get the same today with the DELL M6000 series from off-lease places for $600-$800 if you look around. I got two top end DELL M90s at the time and they came fully loaded with software ready to go. Both still had DELL WARRANTY left on them... This is what we used in my working years so had alot of experience of living with the same DELL M90 machines on the road...
Kinda neat to see my dual 24-inch computer setup in my off-road POPUP trailer... I have it all setup on a 3/4-inch plyboard laying in the unused tent bed end where our wrap around seating is. Worked out good for us... I can also use the tabletop shown here as well for my computer ops..
