Lots of people who don't want to limit their options end up with 6 bikes
If you're going to do rock-crawling, stream-jumping, mud-slinging, bone-jarring mountain riding, get a mountain bike. Even if you only do it 2 or 3 times a year. (Mountain bikes are for climbing, descending, rock-crawling.)
If you're going to go on 2000-mile, 8-week self-contained road tours, with all the accompanying gear, get a touring bike. (Touring bikes are for long-distance, reliability, comfort, stability, load carrying).
If you're going to spend your time going fast on paved roads with little or no loads, get a road bike. (Road bikes are fast, nimble, lightweight, finely balanced.)
If you need your cycle to fit into a low-impact lifestyle, and to be a capable, comfortable, human-powered vehicle, get a recumbent. (Recumbents are a lifestyle, for extreme comfort in the places where upright bikes hurt the most. Recumbents and uprights are very different, in handling, in visibility, in muscle usage, in maneuverability.)
If you're going to spend most of your time commuting, in all conditions -- sun, rain, dark, cold, traffic -- get a commuting "city" bike. (Hybrids are a compromise in geometry and compoments, to make them agile, rugged enough to carry stuff over rough roads, comfortable and visible in traffic.)
Similar dilemna: You want to get into snow sports? You can buy alpine skis (=road bike), cross-country skis (=touring bike), snowboard (=mountain bike), snow-skates (=city bike). Or for a different experience, to concentrate on getting down the slope in comfort and style without fear of bruising your bum, a sled (=recumbent). This is just an analogy.... nobody can tell you what experience you're looking for.
I could never use my touring bike for daily commuting. But that's just me. I couldn't stand the sight of it caked with dirt and crud, the rims worn down by braking in traffic, the gears needing replacement twice a year. But the truth is, a touring bike could handle that -- and road rides -- just fine. My commuting bike needs lots of maintenance, I want my touring bike to be ready for a 4-day trip on a moment's notice.
I still think you'll be fine with the San Anselmo, if your primary purpose is commuting. I've seen lots of people on week-long tours on hybrids; it's not ideal, but it's not your primary purpose. For self-contained touring, as long as you can attach a sturdy rack (you can get clips for that purpose for the front fork, too), you'll be OK.
