I've been tempted by those gloves. Instead of splashing out for them, I tried to use a pair of those stretchy ones (magic gloves?) for typing. We've had our computer in freezing places since I've moved to the UK, and the pair I have are thin enough to be great for typing. They aren't super warm, but they work in a chilly home.
Today's weather sort of reminded me of something regarding dehumidifiers. I don't know how much this applies in the upper levels of a building, but I've found that you need your dehumidifier the most on the first sunny day after a string of rainy days. If you're trying to only run it sometimes, on rainy days maybe run it a few hours, but on days when things are drying out, run it all day. Evaporation can cause a lot of vapour to run into the air. I also don't tend to stick a lot of stuff to dry on my rads unless we have a ton or we need things dried really fast. By doing a load every couple of days and letting it dry a bit more slowly, it helps the dehumidifier to do its job better. When weather permits, of course, I always stick things outside to dry.
