"touch" meaning the filesystem command? yes. meaning "touchscreen"? yes, but drivers for the specific touch device (screen) may/not not be shipped by default with whatever distro you choose.
I have a Wacom tablet that "just works" out-of-the-box.
Installing stuff is not difficult, however. Linux invented the "package manager" concept.
Graphics is one area where you might need Win/Mac (or, at least, WINE; which is a windows API compatibility layer). Major players (Photoshop, etc.) don't support Linux. There are alternatives for basic graphics work (Gimp, Inkscape), and things are getting better by leaps and bounds. I do a fair amount of image manipulation, vector art, 3D modeling, and even a bit of video editing using various Linux programs. Of course, if you really need Windows for something-or-other, most computers are powerful enough nowadays to just run Windows in a virtual machine, as needed.
Interoperability is great, however. Linux can manage a wide variety of filesystem formats, and there is software (free, open-source software, even) that can work with the file formats other use. LibreOffice, for example, is pretty much a drop-in replacement for the entire MS Office (extra features too), and can read/write .doc files (in fact, I've recovered corrupted .doc files that Word couldn't open). ffmpeg covers just about anything audio. Even PC gaming support is getting good.
