Maybe I'm missing out, but I've had my 1080 for a couple of years now, and I've not taken it onsite yet. At 70 lbs or so, it's a bit heavy and bulky. No way would I travel without my tablesaw onsite as well. Having a jobsite tablesaw allows me consistent & fast ripping ability of any length as well as allowing me a router table onsite in the extension wing for edge treatment or making custom mouldings onsite.
Used it to take some 1x8 and 1x4 Poplar to make some custom profiles for a wainscoting job a few months back.
Here's my jobsite saw setup: (actually two setups - old Bosch saw and the newer model)

The other day I was building some plywood mitered stairway posts, about 8"x8" wide. Trying to do that with a track saw would have been maddening. But with a tablesaw, it was quick and accurate.
I use my Festool TS55 and rails for just about every job, but to suggest they supplant a real tablesaw setup is ridiculous for a remodeling carpenter imo.
Like the guy here making drawer boxes with his TS and Domino -- could make them in 1/4 the time with a tablesaw and router table.
Next time I do some built-ins, I'll probably bring along the MFT, but as a day-in/day-out bring the worksite work surface, it's not worth bringing unless you really need some wide crosscutting ability.
I like green and black stuff as much as the other guy, I just not as gushing about it as most here, and there are, believe it or not - sometimes better ways to accomplish a given task.
