Usine in a live laptop environment. What's needed to extract full use

[theprep]

I use to dj, have gone back and forth about returning to vinyl. But decided I rather have more control over my music selection, utilizing my own productions. Is Usine Pro a good choice with an Akai MPK49 and my Fab Filter plugs and a load of samples? I want to do a live show. For the add on packs, do I need a touchscreen to take advantage? Obviously similar to Flying Lotus, Teebs, Neon Indian, Tycho etc

Looking at the news Dell XPS 15z. Long time Mac user, over it. Please provide some examples of a compact portable live setup.

I have been watching this app, amazed at how much it's grown/matured.
