I frequently take the Keystone and NE Regional PHL-NYP and find that I can only work ~20 minutes until I get motion sickness. I'm fine if I stop using my laptop.

I'm considering taking the Acela BOS-PHL for an upcoming trip, and am wondering if motion sickness tends to better or worse on the Acela. I'm hoping I can work for at least half of the journey. I have an upgrade to F if that makes any difference. Otherwise I'll probably have to fly.

Does anyone get motion sickness who has taken both the Acela and NER? Which was better?
