Using Thinkpad Trackpoint USB Keyboard with MacBook Pro, Air, Retina (with pictures)

Question

Using Thinkpad Trackpoint USB Keyboard with MacBook Pro, Air, Retina (with pictures)
The purpose of this discussion thread is to:
(1) Get community thoughts around using alternative and complimentary mousing approaches with MacBooks 
(2) To share a current and searchable set of resources for those interested in leveraging a best-of-both-worlds approach for using a non-Apple Trackpoint Keyboard with an Apple MacBook.
(3) To level-set the fact that a Thinkpad Trackpoint USB Keyboard works with MacBooks automatically and instantly out-of-the-box.
Note: I created this discussion because I found that all the other discussion threads related to using a Thinkpad Trackpoint Keyboard with MacBooks were archived and therefore I could not post my thoughts there.
I have been using MacBooks for 3+ years now.  Airs, Pros, Retinas etc.  I LOVE the built-in MacBook Apple Trackpad.  It is wonderful.  Apple has no equal as far as Trackpads go.
In addition, I have been using the Thinkpad Trackpoint USB Keyboard with my MacBooks for ~2 years, and below is why I have found BOTH the Apple Trackpad and Thinkpad Trackpoint to be great.
The Trackpoint and Trackpad both have their sweet spots.  Personally I use the built-in Apple Trackpad on my MacBooks when I'm using my MacBook for less than 1 hour, loosely speaking.  If I am going to be heads-down for more than 1 hr writing, reading, surfing, graphic designing, programming, workshop facilitating, teaching, mindmapping, presenting, demoing, etc. then I pull out my "Lenovo Thinkpad USB Keyboard with Trackpoint (55Y9003) > https://www.google.com/search?&q=lenovo+thinkpad+trackpoint+usb+keyboard
I know many will laugh at me for using a Thinkpad Trackpoint Keyboard with a MacBook...  Keeping an open mind, let's just agree that there is historical precedence for alternative mousing devices.  If I could only choose one, I would use the Apple MacBook built-in Trackpad exclusively, however with alternatives come potential benefits.  Keep in mind that Apple, Microsoft, Logitech and many other companies make millions of dollars each year providing alternative peripheral devices for computers, and mousing is no exception.  Regardless, I just want to share my positive experiences using both. :-)
Why should you care?  For *some* people the following is true and meaningful.  The Trackpoint (the little red eraser head stick thingy) in the midle of the keyboard enables useful and unique dynamics/use-cases, including:
You don't have to take your hand(s) off the keyboard to mouse
You can independantly click without accidentally moving the mouse (Yes I know some people don't have issues with this)
You don't run out of finger-gesture runway when you're moving your mouse across the screen (I know this is a gray area for some people)
For mouse-movement-heavy applications (e.g. Graphics, drawing, etc.) the Trackpoint *is at times* more exacting
Below I share some pictures (which I know *look* ridiculous to some people, but none-the-less help demystify what this looks like.  And, while ridiculous looking, it is actually quite thin and elegant once you get over the initial shock of seeing these two diverse technologies combined in this way.
Rest assured, the keyboard shown below (google "55Y9003") is VERY light, thin and fits in almost any laptop case/backpack easily so it is not a big deal to carry it, if you work on-the-go.  In addition:
It is UNCANNY how well it fits on top of the keyboard space of all MacBooks. 
It fits perfectly around the corners of the MacBook Pro/Air/Retina keyboard
Note: I took one of the 5 rubber feet/pads off the bottom of my keyboard, the one in the middle
Lastly, you can actually use the built-in Apple Trackpad at the SAME TIME as the Trackpoint Keyboard. 
It is quite a nice best-of-both-worlds approach for people that like the benefits of the "Why should you care?" use cases above.
Please reply and comment with your thoughts and please let's keep it positive, constructive and friendly :-)

My two Retina MBPs, one with and one without the keyboard, so you can easily see the difference.  (As if you wouldn't)

Answer 1

Newer Bluetooth version of the ThinkPad External Trackpoint Keyboard available...
The new version is smaller, so you can use your MacBook Trackpad at the same time as your Trackpoint keyboard.
Here is the Lenovo model/Part Number# 0B47190
Here is a picture of what it looks like:
Note: Just like the older larger USB model keyboard, there is a rubbery footpad in the middle of the bottom of the keyboard that I just peeled off.  Otherwise, it makes the "H" key press accidentally under-neath the keyboard.  Once I took that off, it fit perfectly over and around the built-in MacBook keyboard, so I can optionally put it on top of my MacBook for easy typing. :-)
