Using different bluetooth mouses and keyboards on a MacBook I was wondering if it is possible to get a wireless mouse and keyboard less expensive than Apple's that would still work the way Apple's do - without the need to use extra USB toggles for bluetooth connection? 

My MacBook Air has only 2 USB ports and connecting a mouse and a keyboard would leave me without either one or both USB ports. 

I know it might be reasonable to buy some device to get 'more' USB ports, but I'd like to find out if there are any mouses and keyboards on a market that a MacBook would recognize without the need to use their own USB bluetooth adapters. Thanks in advance!
Yes, it's possible. You just need a proper mouse/keyboard that is intended to work that way (via bluetooth).
I know that logitech actually has some of these.
A quick research give me this or this.
