Anyone trading on the road using wireless laptop? Maybe trading from city hot spots? I know the The Miami-Dade Public Library System offers free WiFi at all its libraries, and anyone can use it with a WiFi-compliant, IEEE 802.11b or 802.11g wireless Ethernet device installed in their laptop. How well would this work for trading (buy & hold for 1/2 point intraday, no scalping). I have only used DSL, never used wireless.
