Thanks for the input, however no one in the family has ever complained about accidental key presses on the remote, the buttons are a bit stiff and the edges around the remote's keyboard are somewhat raised so that when it is being held face up it isn't pressing the keys on the back as you press on the front buttons.
Having a physical keyboard vs using the Kodi on screen keyboard is miles apart IMO, pressing a letter key is much faster than using the arrow keys to get to each letter. It also much more convenient for kids and non-techy people to just type using a physical keyboard then to use the OSD keyboard. Sure if it was a touch screen keyboard like in many Kodi app's I'd agree with you, however between the Kodi OSD keyboard or physical keyboard I would pick physical any day.
To each there own I guess, but it would be nice to have this option for people like myself that want one. I will hold on to the Boxee remotes as long as I can, this is the best remote IMO and should you decide to add a keyboard to the OSMC remote I'll be first in line to buy one.
As for the design, the Boxee remote is super slim so it is achievable, I cant compare to the OSMC remote but it's not much bigger than the apple tv or fire tv remote, slim and small enough that my 2 year old can hold and operate rather easily.
