I have been using Logitech diNovo keyboards for years and love their form factor (separate number pad) since I can fit both keyboard and mouse on my slide-out keyboard tray. The only downside is Bluetooth, which is not so reliable on the Windows computers I have been using. I am starting a new job and am looking for a compact keyboard without a numeric keypad that I can use with a keyboard tray. Based on my experience with the Logitech keyboards, I am thinking I will avoid BT keyboards if possible and go for wireless RF keyobard instead, or if there is no alternative then a wired keybard. I am finding surprisingly few alternatives. I am looking for suggestions other than the Logitech diNovo Cordless Desktop Keyboard for Notebooks (http://www.logitech.com/en-gb/433/134?selectedcrid=433&selectedcid=134&WT.z_sp=Product&osid=&bit=
) which while it looks like it could work is expensive in spite of the fact it has been discontinued and gets mixed reviews for poor build quality and for the mouse.
I do not mind if the keyboard is supplied without a number pad since I could probably still use my Logitech Bluetooth number pad when I need to.
