I only bought a Festool Domino because there's literally no other tool that does that. It's amazing; the thing is like cheating for panels or for trim. Everything else is a mix-and-match. My tracksaw is a Makita (uses the same rails as a Festool, feels fine, isn't Quite As Nice). My shop battery tools are DeWalt, my house battery tools are Skil 12V (which are really nice for the price, even if they're not as small as other 12V brands). My tablesaw is a Delta (also sold as a Ridgid). Though I've thought a lot about going to Festool for a hand sander, mine are...Bosch. ;)

I do agree with your friend about dust collection though, which is why I use the tools I do use. Dust is the absolute worst, and it is worth spending money to solve that problem IMO. The thing about Festool is that it's good at solving those problems portably, and in that light they're not that expensive. I've also gotten into 3D printing I've been building better dust accessories for my other stuff. (For example I've got a set of 4" dust couplers in development that are a WIP but are noticeably better than any of the options I have found online for a reasonable price and that work in a home shop without ducting.)
