Time to give up on Logitech Wireless Solar Keyboard K760 ... at least not for home use

Logitech Wireless Solar Keyboard K760 is supposed to be my "dream come true" keyboard for home use mainly because of the Bluetooth keyboard switch feature.  This feature should allow me to switch between using my Windows 8.1 Dell PC and my MacMini at ease.  It turns out that I super rarely use that feature.  My MacMini is rarely turned on these days as I don't need to code in XCode anymore.  But that's NOT the reason why I finally give up on using Logitech Wireless Solar Keyboard K760 at home.

The mainly reason I can't use it at home with my Dell PC is that:

• The keyboard lost connection frequently, and I had to use my mouse to navigate to the Windows 8 charm, select device, and force the system to re-recognize the Bluetooth keyboard again.
• And sometimes even that failed, and the machine will suddenly crashed, gave me that notorious blue screen of death.

The frequently of that blue-screen of death is getting so ridiculously frequent that I had to switch back to my Microsoft Sculpt Mobile Keyboard.  In fact, I actually like using this keyboard at home better since it:

• has small form factor
• has all the key that I need to use in Windows environment
• actually more comfortable than Logitech K760

I am not quite sure if the problem was on the Logitech K760 keyboard, on my Dell PC (particularly the bluetooth drive), or what.  But if the Microsoft Sculpt Mobile Keyboard eventually having the same problem (losing connection, crashing the machine), then I think it proves that I should just stop using Bluetooth on my Dell desktop all together, and just switch back to regular radio signal wireless keyboard, which seems to be extremely reliable.
