"Single-use" may have been the wrong expression. I meant, I needed something that could break, be stolen, or tempered with at the airport, without me losing trust/access to my main work/digital life tool, and without me getting too sad about it.

I try the Macbooks' keyboards every time I see one in the store. Yes, it has been even worse, but the new ones feel clickity-clackity, like an ATM pad, to me too. No travel, and annoying high pitched noises. Feels weird to rest your fingers on those keys. Not even close to a Thinkpad keyboard, old or new. I could get used to it, but it is not a great input device. Not at all. Trackpad rocks of course, but so does the nipple, if you type a lot.
