Fair. I struggle with getting touch screens to recognise touch sometimes, but I've habituated to them over the years. I did contemplate getting a cue-cat to replace my existing barcode scanner (which connected by some connector that went out of style in the late 1990s/early 2000s; the computer I built in 1998 had one, but nothing newer I've used), but there was some issue with shipping them to Australia, or of getting them at all.
