I wanted to get a Lappy Backpack but one which can be used with formal wear as well. So essentially I am looking for one with removable shoulder straps, which can also be carried like a laptop briefcase. My friend had one such bag (a Samsonite). Trouble is he doesnt know the model. Does anybody have anything similar? (doesnt necessarily have to be a Samsonite). Would like to know the make and model if so. Have searched a lot on the net but cant seem to find anything
