Processing power is certainly enough, and there are some really good apps that vtake advantage of that and the form factor, like Pixelmator and Affinity Photo. The latter especially, is more than enough for almost everything, it's somewhere inbetween lightroom and photoshop (closer to photoshop), but smoother and with much better interface.
The weak link by far in a travelling setup is the scanner. They're big and bulky when it comes to medium format, and they require a PC to drive them.
Second issue is development. The easiest way to do it is to travel with some powder developer for B&W and powder fixer, mix them on the spot, use them while you're there, discard them when it's time to leave. Colour is a bit more hassle, because you can only get liquid concentrates and not powders (and remember the 100ml rule when flying with carryon bags). Then there's temperature control.
The easiest way is to find a local or mail-in lab to do your colour work. Or, if you're staying at the place for a couple months, order online the chemicals to be delivered at where you'll be staying and give it a try yourself.
