I get device 'lust' so to speak often... Yet I rarely am able to act upon it.
I do however collect any technology that it's former user wishes to be rid of, and use that. That's how I acquired my Clie, (very elderly) box, 5-year-old laptop, and this 2-3 year old tablet... o.O The only new things I've managed to ever have around me are my Powerbook and my Zaurus...
However I am a bad person when it comes to early adopter-ship for software... OSX 10.4 the day it came out, upgrade regularly all my apps, even to betas/alphas sometimes... And of course sometimes I get burned by this habit. Other times it works fine. YMMV, of course.
