Are there any regular Chicago Metra riders here? I'm going to have to start commuting downtown regularly in November and am looking to obtain a mobile hotspot so I can work on the 90 minute Metra ride. A year or two ago I had Sprint, and tried tethering but the experience was awful. I'm not looking to repeat that experience, so between AT&T, Verizon, T-Mobile, or an MVNO, I'm curious what provides a usable experience for routine web browsing.
