gotfork writes: Several years ago I injured my wrists while typing at a poorly set up desk. I am now greatly recovered, and can work at a desktop computer for several hours each day as long as I wear wrist braces. I have avoided using laptops in the past because both TrackPoint-style pointing sticks and touch pads create a lot of strain on my wrists, but am ready to give it another shot. Is my best option a stylus-based convertable tablet/laptop (such as the Lenevo X series) or are there any lighter-weight devices that have ergonomic inputs?
egrep patterns are full regular expressions; it uses a fast deterministic
algorithm that sometimes needs exponential space.
