Due to the failure of laptop while on the road I picked up a asus eeepc 900, 1 gig ram 16 gig solid state HD. I have managed to load SA 2009 plus Topo 7 and copilot 11. I have the phone data on a 4gig sd card and cannot have all the topo regions loaded. Performance traveling with SA and copilot running seems to be good. I am using one of the short usb BT adapters to tether my Palm 700wx while traveling for weather maps.
