Non-AT Model Fs and their hat keys. Sometimes super long.
I mean look at that * key on the bottom right corner. It's 3 keys wide (or tall rather), but the real key area is only 1 key, and if it's anything like my 5291-2 F, it ain't stabilized at all.

.
I also despise single-sized backspace. I hit most of the extended keys (shift, backspace, enter) on the edge, so I don't think I'll do ISO too well either.
