I felt the same about iTerm until I started using it, and still feel the same about Alfred (have it installed but reverted to using Spotlight instead).

iTerm's great for the features it has that the regular terminal doesn't. Fullscreen borderless, universal hotkey to reveal, more configurations for workspaces, and I much prefer the paneling/tabs setup with iTerm too.

I assume the same argument is used for why Alfred is good, but I've never really gotten into it. Anyone mind trying to sell me?
