^ Pretty much tells you everything you need to know.
A right angle connector at your recorder input can be nice because the torque that's put on the cable when it gets pulled on doesn't necessarily automatically work to pull the connector out of the socket. With a right angle connector, it's also convenient to put a rubber band around both my handheld recorder and the cable. This provides ample stress relief on the connector and socket for any cable pulls that may occur, since you're pulling on the rubber band instead of putting stress on the connector/socket combo, not to mention helping to keep the cable from being pulled out.
