For the mini sure, but it's a massive pain having an external drive for a laptop. I use one all the time and as well as being waaaaay slower even with a good drive, I lose it all the time.
Yeah it's not feasible at all to use external storage on a two port laptop. Dongles that allow you to plug in power and monitor are still just not reliable enough for storage, the only reliable connection I can get on my 2 port MBP is with a dedicated Apple USB-C to A adapter.
Shocked they're still selling the two port machine, it's been nothing but hassle for me as someone who has to use one.
