Looking for Wireless Keyboard Recommendations

[ColdPixel]

I currently use a Microsoft 6000 bluetooth keyboard.  For me, it has the following key features:

• Curved key layout
• No palm rest
• No numpad
• Full sized keys
• Wireless

 

I have been using the keyboard for years, and lately I have started to have connection issues, and I wonder if perhaps the keyboard is wearing out.  I have searched high and low, and cannot find another keyboard on the market with the features above.  There are many that meet every feature except that they are not curved/ergonomic.  Ideally, I would also like the keys to be quiet and low travel (e.g. similar to laptop keys) but I'm open to considering a mechanical keyboard.  I am also open to ergonomic split layouts - but it needs to be one piece (not two completely separated keyboard halves) because I type with my keyboard on my lap and I cannot balance a half-keyboard on each leg.  Bluetooth is ideal - and multi device is even better (I use multiple computers, and currently have multiple Microsoft 6000 keyboards), but I could settle for a dongle. 

 

Thanks for any recommendations!!
