I tend to stick them in my "Technical box" (Large plastic storage box with all sorts of cables, connecters and crap in there), I have to admit when I retired my HTC HD2 I put it in my new phones box as I loved the design and thought I could consider doing something with it, like installing Android, Ubuntu or even 7.5 on it, but as soon as I got my hands on my 1520 all thoughts of wasting my time on it vanished :angel:
