I've been using the keyboard for most of the day. Here are some initial thoughts, particularly to serve those of you who use a Mac.-the placement of the CTRL/Alt/FN/Command keys is off from the Mac keyboard and makes quick tasks, such as copy/paste difficult.-The pageUP/pageDown keys work as expected when scrolling the page up and down.-the Home and End keys work in Microsoft Word. Not in Apple Mail, Safari, etc. As I type this review, the Home and End keys are working as Page Up/Dw.-I do like that the sound, pause, etc keys work with the press of the function button. Works just like my Mac does.-I love that the keyboard has an attached number pad, before this, I was using a separate device-the keys are mostly easy to press. They are harder than the Mac keys, but not cumbersome.-I didn't need the mouse (or want it); however, you need to add batteries to it and turn it on for the keyboard to work. Now, I've got it stored away and turned off in a drawer. -there are some keys on the keyboard that we cannot use (as Mac users, I'm sure).I'm not sold that I love it for the price I paid. It wasn't terribly expensive, but I never wanted the mouse, so it's more than I wanted for a keyboard. Plus, with home/end keys (which is why I chose this - that and the pink color) not doing what I want everywhere and the CMD key not being where I need it to be, I may use my free return.It is a good keyboard, but if you're an avid Mac user, think about it before you hit "buy it now."
