I'm stuck with the original-issue Mark I head -- which is a pity, since I have a migraine of remarkably dizzying intensity. I have taken OTC pain and allergy medicine and promised myself that as soon as the symptoms fade a little, I will rinse out my sinuses. The wave after wave of rain and the pressure fronts that drive them are playing a big part this, I hope, and clearing things out should help.
Meanwhile, I managed get my desktop to run long enough to grab essential Firefox stuff and the Downloads, Documents and Pictures folders. I'm on my backup (Windows-lite) laptop and my pandemic-indulgence MacBook Air for now, which gets me just about everything except the big screen. Fiction and writing-related stuff was already on Dropbox, since it allows me to go between Windows and the MacBook almost seamlessly. I've got a replacement desktop machine on the way, and there will be a certain amount of rebuilding once it arrives.
