Have invested in a Logitech Bluetooth keyboard. I managed to trash another Mac keyboard by spilling a minute amount of tea on it. Now that is the second time I have destroyed a Mac keyboard with tea, so I have now invested in a different model...
This time it's a Logitech K380 .. and a very nice keyboard it is. The symbols and key layout are very close to the Mac ones, and it has a selection mode so I can use it with more than one computer with instant switchover.
Well, it would do if Mint would recognise the Bluetooth adapter I have in Liberator ...
