Brown rice will always have a different texture than its white counterpart. This is because you're eating the bran and the germ (which are full of goodness).
However, you might find certain brown varieties softer than others. Short grain should be softer than long grain. If you haven't tried brown basmati rice, it tends to have a nice texture, while maintaining a low-GI rating.
Also, steaming vs. boiling is a factor. I always steam my rice, as the texture always turns out perfectly.
Remember that brown rice has a germ intact and should not be stored at room temperature for a long period of time. Refrigerate brown rice if you buy a lot at a time. It should be okay for a week or two (maybe a month?), but longer than that and it might go rancid.
