system
You are a helpful assistant. The assistant first thinks about the reasoning process in the mind by using Belief-Desire-Intention (BDI) framework and then provides the user with the answer. The reasoning process and answer are enclosed within <think> </think> and <answer> </answer> tags, respectively. 
Below is an instruction that describes a task. After thinking, when you finally reach a conclusion based on the customer's intention, desire and belief, clearly state the BDI thinking process within <think> </think> and then the answer within <answer> </answer> tags.

User Review: The Canon S40 is a superb digital camera.  First, the exterior: The S40 is compact and can fit easily in a jacket pocket (though not in a pants-pocket - for that you should check out Canon's digital Elph line); it has a convenient clamshell design; and unlike many of the other digital cameras I examined it is made of polished metal-not cheap plastic.  This is sturdier, feels better in the hands, and looks a whole lot sleeker.
Second, the interior: The S40 takes 4.0 megapixel pictures, which look great on any computer screen and will print out very nicely up to 5x7 and even 8x10.  Its ability to capture color is far superior to most other digital cameras.  Most of the control menus are reasonably easy to use.  It is packed with pre-set photographic options (for action shots, portraits, etc), but has full manual override for those of us who grew up on old-fashioned SLRs.  It also focuses much faster than many of the digital cameras I've seen - helpful for capturing wildlife or childrens' sports events.  Finally, the included battery is surprisingly long-lasting and recharges (with a very compact included recharger) quickly.
Third, the software:  The S40 comes with Canon ZoomBrowser (for viewing) and ArcSoft's PhotoSuite (for photo-editing).  I find ZoomBrowser intuitive and can easily organize my photos, however it sometimes has problems printing on my inkjet printer.  The ArcSoft program is much less capable than Adobe's PhotoShop, but can delete red-eye (or unwanted individuals at the edge of a picture) without too much trouble.  On the whole, both should be adequate for the casual user.
Are there drawbacks?  Well, yes, there are several.  Like most digital cameras, the S40 sometimes has problems focusing on the correct subject and, in automatic mode, often opens the aperature too wide (resulting in a narrow range of focus).  There is a way to manually focus the camera, but it is not terribly effective.  It is also impossible to attach separate lenses - but that drawback is common to any digital camera of this size.
Bottom Line:  Despite the drawbacks, this is one of the best digital camera's I've seen.  It is conveneint, well-built, and easy to use out of the box.  I've already dragged it to Vermont, Atlanta, central Africa and Australia without a hitch-not to mention that I can take it on my frequent bicycle rides closer to home.  I'd be happy to send a sample photo demonstrating its resolution and color-capturing abilities (about 1.2 MB) if you ask.  On a final note, I would suggest buying a 256MB (or larger) compact flash card.  This will let you take 200+ max. resolution photos at a go.
