• An active PS/2 to USB keyboard adaptor that doesn't work with my old :CueCat, so I can't use the :cc with my Mac.
• An old laptop PC with a flaky CDROM drive that refuses to read most OS install media, so I'm stuck with ancient FreeBSD and no wireless support until I can upgrade.
• The :cc's stupid habit of typing Alt+F10 before the encoded barcode data, which occasionally gives Mozilla the heebie-jeebies or even accidentally kills it.
• LibraryThing in overload mode refusing to let me log in again.

On the other hand, one of my old bug reports reminded me how to get a SHARP PC-AR10 working with FreeBSD-4.X without much trouble, and when LT deigns to let me log in its import features are really easy to use.
