I trade options and tend to track a set of stocks in my targets' sector as well as the major indexes, so I need lots of real estate for charts. I find 1280x1024 too small, and prefer 1600x1200, so I use a desktop.
I visit my folks one weekend a month, so I miss the first few hours of trading on Monday morning, which is a bummer. One thing I'm thinking of doing is taking the train, and using a notebook and the Verizon EV-DO wireless service, which should give me bandwidth of around 400kbps. Has anyone here used this service and have any comments about it?
