The amount of storage you own (in Terabytes). Personal content (CD, MP3's, digital photos DVD's, etc.) is becoming so numerous and storage continues to decline in cost such that owning a Terabyte or more is becoming not only affordable but required. Add up the storage space in your PC HDD, TiVo or DVR HDD and iPod to see if you own a 'T'.
Q: How many T's do you have at home? A: I've got 5 T's total.
