Are there any major drawbacks to trading all day with a laptop as your primary execution machine ? I 've never had a laptop but if I get one will set it up as a desktop; external keyboard, mouse , additional monitor(s) using Matrox Triple Head 2Go . On very busy days I would still run a Win 2K machine as backup and for extra charts . The laptop wil run on XP Pro and it's not a high end model, regular stuff Intel Core 2Duo, 2 GB RAM, Intel X3100. (I am not sure yet if I should opt for an external GPU instead of Intel integrated GPU, I read starting with 945 chipset it supports extended desktop mode, but I have been told even the current Intel GPU with 965 chipset may be tricky with the Matrox Triple Head 2Go box.) Aside from the graphic card issue is this a wise choice for serious trading compared to a 3-monitor desktop ? I am willing to sacrifice just a little bit of reliability for the convenience of mobility and versatility, I don't use leverage and don't day trade so not too worried about positions jeopardizing equity before I can fire up the back up machine or call .
