My Macbook Air has a buggy spacebar that the local Genius Bar has been unable to fix to my satisfaction. I have to go on a working holiday soon and I'll need a reliable workaround. I have a Samsung Chromebook that does what it's designed to do well enough, but I'd rather have the additional functionality of my Macbook. So I'm wondering if you have any suggestions for a small, lightweight (maybe even flexible?) external keyboard that I can throw into my backpack along with other travel essentials. Also wondering whether I can use the Macbook's touchpad alongside such an external keyboard, instead of buying a separate pointing device for this arrangement. Thanks!
