I use my Incredible for enabling my addictions; mainly reading AndroidForums, trying out any app that sounds even slightly interesting, and playing Wordfeud.
Also, texting, Facebook, Kindle, Pandora (to the point that I am looking into replacing my truck stereo with one that I can hook my phone up to), GPS, making my friends jealous, checking stocks, keeping track of my media collections, taking notes, taking pictures, agenda, internet, school research (at least I did during the last month of spring quarter but I'm sure when fall quarter starts up, I'll be using it then, too), drunk dialing, ignoring housework, news rss, sexting my husband (so he won't complain about the time I spend with my phone as much), reminding me to pick up the kids, and even making and receiving phone calls.
