It's started getting cooler here in brisbane - natives would probably say it's freezing, but they don't know what cold is. I've consequently fallen into the habit of taking long baths in the evening with a good book (long showers are verboten due to water restrictions, and the books don't survive long). I've run out of unread books and decided I need some way of using my Z instead. Yes, I am probably nuts.
Some heavy plastic sheet, a hot iron, and 30 minutes later, and I have a waterproof pouch for my Z which is flexible enough to let me use the keyboard or a stylus easily, but heavy enough that it's unlikely to tear. I've currently got it undergoing leak testing - I put a berocca tablet and a weight into it and tossed it in the bath. If it's not filled with orange foam in the morning I might consider doing a live test...
