I've ordered the Albert & Lovelace Flip covers, and I'm having them sent to my mother's house with instructions to bring them with her in November.
I could not resist them, and especially since I can't tell if they're limited or not - I'd rather splurge now and then slowly shop my stash in the used and cheaper sides of things.
(Plus, c'mon. Albert Einstein and Ada Lovelace... who's going to be next?)
