I be a fan of the Logitech Wave keyboard which have a great key feel and little noise . I need a smaller keyboard to pack for a extended trip , so I get this . it be sadly much inferior . the key be not very smooth and quite noisy . in addition , I have grief get the software to work on my Mac . -lrb- you need the software to bring the command key to the right place and to get `` num lock '' to work . -rrb- I have to pair the device to its receiver on a Windows machine , and then I could not find any software for the Mac to get the key remap . the Logitech web site be a mess . at one place , it only offer Windows driver . another have a option for Mac software but the download button do not work for either Firefox or Safari . I call support today and they confirm . it be Windows only . why ???
