If you are using NetSuite WMS you can expect that pretty much any android/ios device is capable of running the solution. The solution requires 2 bundles to be installed in the account (at least for now): SCM Mobile (1st) and then Oracle NetSuite WMS (2nd). The order of install is important, and I think NetSuite recently clarified this in their documentation.
Devices sold by zebra, honeywell, etc. tend to be more warehouse friendly as they can handle drops better and have built in scanners.
Ultimately, you will just be opening a browser "web-app" that is mobile friendly.
Not sure if I answered your question, but happy to clarify. I can't really speak to any specific hardware selection (e.g., tc51). You can find the minimum specifications required by any device in suiteanswers or the WMS documentation.
