I remember lusting after one of the Librettos back in the day for it's small size. A bit along those same lines, I had a Gateway Handbook that I perhaps should have never parted with. Nowadays I keep the collection manageable by only doing IBM-brand (and some Lenovo) and the PC110 takes away yearning for something like these.
Still, the Librettos we're neat machines and glad you reminded me about it. Thanks for posting!
