How easy are they to cut to size, or if you need to use multiple to cover a window how does the gap/seam look? Have been thinking of getting them, but we also want to replace our windows at some point. I assume you can't just reuse them?
Depends what you want to do. I have installed Linux for some people and they were perfectly happy with it and never touched the command line. While for me barely a day goes by using Linux that I don't touch the command line for something.
Depends, for sober drivers? Yes. For drunk drivers? No.
