Search the forums, that bike has been discussed a good bit. I personally think it is just about perfect. I don't own one, but I'd probably buy one if I had to do it all over again. About the only criticisms I saw were the hubs are cheap and 32 spoke count is not a great choice for a loaded tourer. Also, some people have pointed out that the Sora crankset is not a top-end model, but it will probably last as long as anything else.
I commute on a touring bike and think it is the perfect style bike for commuting. The Sojourn has a lot to offer other other touring bikes. You get fenders and a rear rack included, disc brakes, a Brooks saddle standard.
