I am planning to replace my iPad 2 Verizon 3G with an iPad Air and am trying to decide which data provider to go with. I commute into NYC several days a week on the Metro North Hudson Line and work in downtown NYC. I have been generally happy with Verizon's 3G network at work, but there are many holes and slowdowns on the train line, where I use the iPad frequently. Also, coverage is spotty in some places close to my home and although I usually am on a WiFi network, sometimes the 3G service comes in handy (e.g., during a power failure) and it would be nice to have service that works. I originally purchased an AT&T iPad 2 when I purchased my iPad a couple of years ago, but I returned it for the Verizon version because, although AT&T's service was generally faster, it hardly worked at all in downtown NYC during peak usage times (e.g., lunch). Based on the reading I have been doing, it seems like getting another Verizon iPad may make sense, but I was wondering if anyone else in the geographic area has any experience with it or other providers' services and/or has any opinions. Thanks.
