No-one takes t-shirts seriously - you're wasting your money with those. They're just a winter vest at best. Practical things devs use, that's different. +1 on mugs. To this day, because some real effort went in some multimap mugs are great. Good size quality mug. Possibly even a keyring with a decent amount of weight - making it hard to lose. Or similar. How about a pen that also doubles up as a touchscreen stylus?
