Everyone is a trader.
My work/play-place condition at home is dual display: iiyama PLE2710HDS フルHD 27型ワイド液晶ディスプレイ 【1920x1080/ワイド/HDCP対応/応答速度2ms/コントラスト比20,000：1（最大）】(iiyama-ple2710hds--w1-50406) カラー:ピュアホワイト and notebook display.
On 27-inch diplay, which is my main one, I usually run two softwares for internet. The first one is Microsoft Internet Explorer 9, on which I set up 5 windows (nifty, mail, fb, and so on). The second one is Google Chrome on which I set up iGoogle. On iGoogle, I put several information mini-windows (gadgets): mail, RSS reader, Twitter, and fb, among others. On the display of small notebook, I set up iTunes and file window.
So, this is like a "trader" work-place environment. I believe millions of people set up like this. Thus, everyone is a information-trader. That's all.
