When I first did my first-ever JB (just over a week ago) I did it because I just wanted some interesting theme action, vs. the plain ol' look. I figured if it didn't seem like anything I'd really use, I'd just restore my iPhone. Now I'm using SSH, MobileTerminal, iFile, and all sorts of tweaks to make the phone do more things, and do them easier. (I'm thinking iBlacklist next, to restrict the times certain people can call or text me, muhahahaha...) It's almost infectious, once you see how many more options you have available. For the first week, I bet I was only getting 2-3 hours of sleep every night, I spent so much time tweaking between the time I got home and the time I would finally go to bed.
As much as I liked the iPhone before the JB, and being fairly new to Apple all around, I have to wonder why they wouldn't be all on board with giving us these options in the first place. It takes a really good product and makes it great.
