Computer-wise, for the moment, plenty:
iMac 260 GB
LaCie external drive: 260 GB
PowerBook: 100 GB
5G iPod: 60 GB
Nano: 4 GB
Now unused Powerspec PC running WIN XP: 160 GB
Powerspec external drive: 160 GB
Now, obviously, the memory capacity on each of these is already being filled up, but that's what the specs are for them when brand-new. As time goes on and the hard drives on my iMac and PB start to get a little crowded, I'll probably need to add another external drive.
That's how it goes with my computer storage. Now, when you talk about storage space in one's home.....ouch! I'm in a condo apartment, and boy, it's crowded in here by the time I've got computer stuff, photography gear and, oh, yeah, the basics of everyday living such as furniture...
