I am looking to replace my wireless Apple keyboard with something a bit larger, a number pad would be a plus. I have read the various threads in this forum, there is one keyboard of interest, the Logitech K750. The downside to the K750 is that it is not Bluetooth. I can live with the K750 if there is not something else that is similar in design,appearance and functions. If any of you have recommendations on a keyboard, I would be grateful. It will be for application with a 27" iMac. Thank you for your time and feedback.
