There is still no Wi-Fi on the northeast corridor Amtrak trains that carry hundreds of thousands of business travelers each day. So quit whining and get a USB 3G modem. It’s free with monthly service, which is tax-deductible. For the $60/month I pay Verizon, I can connect my laptop to the internet from any train, bus, boat, lounge, lobby, conference room, coffee shop, or just about any other environment to which modern business takes me.
Free advice: buy a dongle
