Strengths: Lightweight, comfortable, great for commuting/weekend paved or crushed gravel trail rides.
Weaknesses: Out of the box, cannot adjust head piece, separate part must be purchased and installed at bike shop.
I just purchased mine, and have ridden it enough that I can safely say I am in love with this bike. I tried one of the higher end Sirrus models, and the only difference I noticed from those was more speed and nimbleness. This bike is a great balance between a road bike and a mountain bike for sure. Great on uphills with the 24 speed gearing. My old Huffy was nothing like this, and I love the quick access to the shifters over the twist shifts of my old bike. A great value for sure!!!! Love the lightweight aluminum frame and everything about this bike!

Weaknesses: Front derailleur, lack of hand positions
I setup the Sirrus as a commuter - for commuter specific modds, see http://treadrightly.blogspot.com/2013/01/specialized-sirrus-my-daily-commuter.html

Strengths: It is easy to jump on a go. I have had road bikes, and this compares.
Weaknesses: After riding a couple of years with the flat bars, I put some "apes" on it and now it is perfect. Ok, it looks a little goofy, but it is so comfortable I can ride all day.
A great bike for what I am doing with it.

Strengths: Good frame
Weaknesses: Gears, breaks, tyres
This bike is made using cheap parts. Although the frame is well made the gears have broken consistently in the six months I've had it. Plus I already had a puncture - this with wheels supposedly made with kevlar.

Strengths: The ride is comfortable without being a comfort bike. The frame geomety provides for just the right combination of bump absorption and speed, as long as you don't over-inflate the tires. The upright riding position lets you look around when you ride instead of staring at the concrete, and the wide, flat handle bars allow your upper body to relax when pedaling, which for me means I don't get nearly as winded as when I was hunched over a road bike.
The bike doesn't have the twitchy steering of a road or mountain bike, and holds a straight line well due to the forgiving angle of the front fork, which greatly reduces mental fatigue. You can go on long rides without feeling like you've taken a beating, and actually feel like you're having fun instead of working. Sometimes I find myself trying to lean forward and push the pedals a little more than I should, but on this bike I always end up leaning back into the comfort zone and peddling within my ability. If you want to go as fast as possible there are other bikes for you, but if you want to go fast enough then this is the one.
The frame itself is well made, without the mountainous weld seams found on lesser bikes. And I like the style of the frame very much - it doesn't look like anything else out there. Mine is black and has a nice gloss to it; it's the only bike I ever felt like waxing like a car. The alloy forks don't look as nice as the carbon forks, but if the carbon forks actually do soak up the bumps, the larger tires of the base sirrus models more than make up the difference (again, as long as you don't over-inflate them).
I put a Specialized after-market seat on mine because I have never had a standard seat yet that I found comfortable. I will probably change the rear cassette to something more like a road bike's gearing, but that just suits my higher cadence kind of riding. The supplied drivetrain is fine, and lets you practically walk up hills in the lower gears.
Weaknesses: The internal brake cable rattled until I strapped the outside part to the frame. It still makes an occasional ding, but not nearly as bad as before.
This is a great choice for someone looking for a new kind of riding, or who doesn't buy into the faster is better mantra.
