When people start searching for upgrade or replacement of favorite trackball, it's often desirable to see potential candidate together with old one, just to get very basic impression of how similar (or different) it is.
I'm starting this tread with Elecom Deft Pro M-DPT1MR versus Logitech Cordless Optical TrackMan T-RB22. They are very similar ergonomically: 8-button wireless devices with scrollwheel and 44mm ball on ruby gliding beads. Images are slightly overexposed due to the prevailing black color, to provide better detailing.
