Our company is looking to invest money to buy some tablets for field use. We're looking for recommendations based on what you guys have tried and are actively using as a daily tool using ArcPro, Survey123, and Collector app. Most of the areas we service have poor service connection so we would need a reliable GPS/satellite signal either built-in or external to collect points.

Maybe a Microsoft Surface Pro or something that acts like a PC and is also portable. These threads support a MS Surface:
