Going for the DiNovo desktop is not at all bad idea. Thanks for the suggestion. Seems like there's no other Bluetooth enabled Numeric Keyboard on the market anyway. So until someone markets a travel-friendly version, the DiNovo could be an interim solution. Even if it is not travel-sized.

My desktop keyboard is getting old anyway, so one day I'll have to replace it. And when traveling, I could leave the DiNovo keyboard, mouse and Bluetooth hub in the office, and just take the numeric keypad along.

-I guess you can use the DiNovo NUMERIC KEYPAD indepently from the mouse & the keyboard?
-Does it have a an on/off switch (which stays off even when cramped inside a bag)?
-What is width & length of the DiNovo NUMERIC KEYPAD (couldn't find the sizes on the local Logitech site)?
