It maybe the best interest for most of us to trial run Google Chrome first release test platform before putting it on a mission critical system. Carsten Knobloch from Germany has a created a solution just for this purpose - to fire up the browser directly from a USB stick. You simply unzip the package and start Chroming. The portable Google browser weighs at a mere 11MB, and additionally isolates web history, cookies and cache on the /profile/ folder on the stick. Knobloch's Chrome reportedly has been tested on XP SP3 and Vista SP1.
