I also still have an old 20,000 mAh Anker power bank, and my only issue with it is that the micro-USB charging port is starting to wear out. For the rest, it's still brilliant, and it holds its charge very well while in storage.
In hindsight, I really love the way Vista looks. I don't think I ever used it as a daily driver (I went from the family XP computer to a Win7 laptop, I think), but the glassy transparency is certainly something.
Why is this "a few minutes" and "most of them"? Why isn't it "a few seconds" and "all of them with a single toggle in Settings"?
