Question: What is the length of the keyboard and # pad individually.  Trying to figure out if my tray is wide enough.  Thanks!
Document: Good combo. I have had it for a week and so far I have been enjoying it.Size and fit:The keyboard and the mouse fit nicely on my keyboard tray. The detachable numpad is what I need since my keyboard tray is not wide enough to fit a mouse and a full-size keyboard -- the room for mouse cruising becomes rather tight. Without the numpad, the combo fits perfectly.Keyboard:I really like the split and the shape. The hands feel very comfy.
Increased transcription production. Exceptionally light keystrokes, lessening hand/digit fatigue even on long shifts. Detached number pad allows extra room on keyboard tray. Ergonomic mouse fits comfortably. Have transcribed with several other ergonomic keyboards over the years, and this one is the best by far. Thanks, Microsoft, for an outstanding product!
I mean, seriously -- why does the printed-side (with all that FCC / copyright / model crap) face INSIDE the mouse? (The keyboard tilt is also magnetically attached, which does make things easier)8) My dropped mouse (fell off the keyboard tray) now has a loose piece rattling about and I can't figure out how to get it out
First off, the actual keyboard is narrower than it appears in the pics. It's still wide enough though.I thought I'd hate the chicklet keys but I actually like them. The layout is much better than the Logitech, but then I'm used to MS ergo keyboards.
Lower height, split / tilted design so I don't' have to bend my wrists, and now I can type all day without problems.The mouse is another story. I've tried using it for two weeks to get used to it. I cant' seem to get it at a good angle to avoid bending my wrist. The Microsoft mouse is very slippery, so if I angle my keyboard tray far enough to hold this mouse comfortably, it slides away by itself.
I've had this for a few days now and I see why there are complaints with the function keys. Their design is stupid. They are half the length and half the height of the regular keys. Why??? Since they are thinner they aren't as easy to hit as a normal key. Since they are half the height of a normal key, the edge is thin enough that it gets stuck at an angle when you press on it.
(BTW - the number pad works fine, I just don't have room on my keyboard tray for it).BTW - even if you don't have carpal tunnel (yet), you should really get an ergonomic keyboard like this so that you DON'T get it later if you type very much at all. Your hands are worth it.
That works out nicely since most deskmakers are stuck in the last century with keyboard trays that barely fit modern-day keyboards much less a mouse pad. With this, you can manipulate both the keyboard and the mouse from the the keyboard tray and lower your arms to a more reasonable level (and avoid the shoulder pain). In order to accomplish this, Microsoft needed to make some changes to the DEL-INS-HOME-END-PGUP-PGDN keys.
This keyboard is significantly smaller/less wide than the regular ergonomic keyboard. I will continue to use the keyboard for a while and see if this is simply a need for adjustment and eventually I'll get used to it.Second part of tough love: I would really appreciate some kind of magnetic feature between the add on number pad and the keyboard or some kind of slot that I could attach it to to keep it in place.
This keyboard is beautiful. Its like the classy full sedan from an Italian car maker. I love the feel of the chiclet keyboard and the soft but firm wrist pad.My coworkers love the separate keypad much to my dismay. It keeps being stolen, then the calculator will open and start doing math, frustrating but funny.Now for the bad part. I cannot figure out why but for some reason typing 'CD' rapidly in succession results in 'CD'. It doesn't happen every time though.
Answer: The keyboard is 15 ½" by 8 ½" tall at its widest point. The number keypad is  3 ¾" by 5 ¼". I hope this help.
