You can buy a travel/laptop mouse and those can get pretty tiny, but they still have 2 buttons and a scroll wheel. I find using a single button mouse an interesting exercise - both windows and MacOS are usable without it, MacOS in particular you can still do ctrl+left click to get a right click. It sounds silly but when I use a mouse my left hand is still usually on the keyboard so it's not really a big deal. I haven't done it in years, but I didn't really feel like I missed having 2 buttons and a scroll wheel when I used a 'pro mouse' lol. Now, I could rant for a while about how awful the ergonomics of the magic mouse are!
