technoholic
a person that is addicted to buying the newest technical devices like mobile phones, dvd-players or plasma-screens. These things are not bought because they are really needed, but instead because of their design and the fact that they are state-of-the-art. If the person doesn't manage to find himself something new for a longer period of time, he/she has to suffer from withdrawal.
Man, my dad is a real technoholic. Yesterday he bought himself a new mobile although he already got 5.
