My first MFT was the 1080. I have used it for cutting, routing, temporary layouts, assembly and horizontal storage port (as is the case with every horizontal flat surface in my shop)
I have just recently begun rearanging my shop to make better use of the MFT 1080. The first step was to remove my Table Saw into temporary storage. i am hoping i will not have to resort to moving it back into the active shop area. Previous to that move, i acquired the MFT 800 for use when i move my work outside of the shop or into my living area. With my other Festool toys and the MFT, the dust collection is so good, i do not get one peep from the "Management" about all the dust in the house, of which there ain't.
Actually, your own immagination and experience are the limiting factors to what you can do with the MFT's. Oh, and i have just clamped on the VL 700 table extension. I have not had a chance to use it, but it looks to have been a sensible purchase. Especially for controling longer cutoffs. I have mouted it to the 1080 and it looks worthy enough that i will be getting one to increase the size of my more portable MFT 800.
