.. or the same folks, at a different life stages.
I used to love to own stuff. Had great pride of my mp3 collection with pristine ID3 tags, my Star Trek TNG collection, or the piles of magazines and books...
After my last couple of moves between cities, I got tired of having to carry stuff around. Or to keep things organized, sync'ed, backed up across multiple devices. What a waste of time and money.
Can't say I won this battle yet, but at least I started to be more rational. Started donating half my books, and only purchasing ebooks (except for programming languages; still prefer the dead tree version). Also gave away DVDs, almost all CDs (still need to rip a few rare ones before giving away). Threw away most magazines, except for MakeMag and Circuit Cellar.
A couple of more moves and I'll be really free :)
ps: speaking of donating stuff, a friend created an awesome startup for exactly that reason: http://www.bondsy.com. Rather useful for things that you still care, but it's time to find a new home for it.
