My prefernce would be to 'do the Dew', (great bike, great spec, great price) but based on your selections, all the contenders look pretty evenly matched, so it comes down to matters of personal taste and fit. For a bike that won't be ridden much, (4 miles/day isn't much), the ease of attaching quality fenders, and a rack might make rim brakes more attractive than discs, even in wet climates. I ride my current commuter (mid-80's junker with flat bars and rim brakes) 12 miles/day rain or shine, and I have yet to wear-out a rim, or wish hard for more stopping power. I've since had the pleasure of discs on my MTB however, so my next roadie (tourer) will have them too. Disc brakes and rear racks can result in some conflict, but there are a couple of manufacturers who appear to have solved the problem.

If it were me, I'd avoid those radial-spoked wheels (too flimsy and high-maintenance) but you'll note that I'm firmly ensconced in the Clydesdale class, so I worry about these sorts of things. I also think that disc brakes are more thief-friendly, too.

Good luck with your choice
