I want to have dozens of browser sessions open, documents open, excel files open, ftp, keyword research tools, adword editor, youtube video page on pause, pandora page on pause, xmsatellite radio page on pause, up to hundred of open notebook files, all that and i can still scroll Amazon book listing and watch movie on Hulu without noticing any lag, speed problem or system slowdown. What kind of spec should I look for in a laptop? I don't really know what to look for. Cache? RAM? Processor type / speed?
