These take a licking and keep on ticking. I use my ediths as my briefcase and carry my laptop, files, etc. in them and have not had a problem yet. Been going on two months strong of daily use and no stiches falling out. Being an atty, I guess I am used to having to lug around a lot so the weight really doesn't phase me.
The only suggestion I would have if you chose to put your laptop in it is to buy one of those protective laptop inserts that are padded and you put your laptop in. I use it in my ediths with no problem.
Was thinking of doing that (put laptop inside bag). Glad that someone already did. What size is your Edith?
Mine is the messenger bag.
