Just a thought that ive been toying with, switching out the optical pad of an htc desire or incredible and placing it into the slot for the trackball on the nexus one. I know that i would lose out on the visual notification effects from the trackball but im not rooted so im stuck with a plain old white light. From what ive read in a few reviews the optical bad is more precise than the trackball, so it seems like a good trade off. I usually do some type of moding to my phone so its not a big deal to me just curious to see what everyone else thinks, not to mention that the very rare Nexus One would be all the more rare and exclusive because of this mod. Any thoughts?
