Everyone has a hobby. You can deliberately not call them "toys" but if you're doing something outside the scope of your occupational or academic responsibilities, then you're playing with toys.
I don't have too many toys, but I do have a severe lack of time for them. My rusty '66 GMC pickup needs thousands of hours of labor to get back into shape, my guitar skills are waning due to lack of practice, my Wii hasn't been turned on in 3 years, and I have spare computer parts lying around the basement waiting for some sort of [mis]use. Only one guitar has any particular sentimental value; the rest are niceties.
