I'm considering purchasing an MX5500, but before I order I need to know how tall the keyboard is at the top where the display console is. If someone who has this keyboard could take a quick measurement from the desk or bottom of keyboard to the top of the display console (highest or thickest point) I would really appreciate it. I have a keyboard tray that retracts under the desk and I have a fairly small space to work with. I really like the design of this keyboard and hope it will fit, but this info will save me time and trouble sending it back if it doesn't. I checked my local Best Buy, but they didn't have it on display.
