I'm not sure if this qualifies as minimalist, but 5 months ago I moved out of my apartment, put everything in storage, packed a week worth of clothes, a macbook air, ipad, ipod and set off around the world.
I used to have quite a bit of "stuff": home theater, nice car, video games, etc. But I don't find I miss it very much at all. If anything, the only thing I really miss is my dog. Right now I'm working on my iPad app at an amazing cafe in Budapest. There really is no other place I'd rather be.
