LOVE IT! 
ok, I have to insert this caveat first: I’ve only had it one day. I will def add to this review as I own it for longer…. but here’s my take on this camera as of day one:
I researched the HECK out of this camera purchase. I was up in the air about this one and the 1100IS. I liked that this one had a bigger LCD screen over the 2.5″ screen the 1100IS has. The 1100IS has an optical viewfinder, but I didn’t find that to be a necessity for me.
One big selling point for the 870IS is the fact that it has a wide angle lens. (and of course the big LCD screen).
The 1100IS is smaller and slimmer, but in all actuality I like my cell phone, camera and other small electronics to not be TOO small otherwise I feel like I’m going to break them, drop them or lose them.
So on to the actual review. I got my 870is home last night and immediately popped the battery and extra SD card I’d bought into it and started snapping away. This camera boots up SUPER quick so if you see anj awesome photo op, you don’t have to wait agonizing moments for your camera to boot up while the moment potentially passes. With the flash on I was AMAZED at how fast the refresh rate was in between pics. (Considering I use to have a Nikon Coolpix 5600 that would refresh in 6-12 seconds this was SOOOOOOOOO much better!)
I snapped some ordinary quick pics of my family and kitchen which turned out great, full of color and clarity. Then I started to get into the effects menus and options.
The Color Accent mode has to by far be my favorite mode to shoot certain scenes with. I took a whole bunch of pics of my moms flowers with this mode (it’s really easy to pick up the color you want to accent once you read how to do it)…. I even took a pic of my yellow lab who wears a red collar and ONLY accented the color red…. so everything (including him) was black and white except his collar was a bright, rich red…. AWESOME picture!
I did get to use the macro mode a few times, I LOVE that mode too along with color accent. You can get SUPER close to your subject, and you don’t lose clarity.
I have yet to take any really good landscape pics or movement pics (this will come in a later update).
I’ve only chipped at the tip of the iceberg of what this camera is capable of doing…. and I can’t wait to figure out EVERY mode and setting on this (for the quick point and shoot person this camera also works because it is simple to point and shoot everyday photos)…. I’m the type who like to play around with manual settings a bit… this isn’t a full blown SLR by any means, but it does have some flexibility to it to play with the settings…. and so far I’m absolutely blown away by the richness, clarity and quickness of this camera.
So far, after owning this camera for one day and getting to play with it for 2-3 hours (read the manual a bit also) I LOVEEEEE this camera! I paid almost $300 for mine at Best Buy, I wasn’t going to take my chances with shipping it from some online store or trying to shop for it at the cheapest deal (cuz you never know what shape that camera is really in when you try and get the cheapest deal)….. I don’t mind the price either because I opened up Best Buys credit card and put the camera, case and extra SD card on it (All totalled about $350 final) and anything over $299 is 6 months no interest. So THAT was a deal enough for me to just get it at Best Buy and not try to find the CHEAPEST deal…..
I’ll write more of a review once I take this on vacation in three weeks and after I’ve had more time to play with it further and really sit down and read the manual about all the settings.
So far this is the best P&S I’ve seen to date!
I wanted to make a note that I read a lot about people complaining about the indoor pics being too dark in the background when you use the flash. Mine works fine and lights up what needs to light up. Of course the background is going to be dark when the flash focuses in on the main subject and lights that up. That just naturally happens with cameras. If I notice any sort of probs with mine I will make a note of it on here. But so far this camera works exactly how I wanted it to, has features I wanted AND more and FAR exceeded my expectations.
Loved the 3 inch LCD screen 
I’ve looked at many new cameras and particularly loved the big LCD and the wide angle option. I’m still getting used to it and need to read more about the features.
Great pocket camera 
Pros: Pic Quality, Wide Angle, 3″ Bright LCD;
Cons: Battery life not impressive.
Good Camera - Quick Enough - Well Built 
I have used many Digital camera, many makes. This is certainly one of the better ones for the buck. Easy to use, great battery life, quick but not great with indoor shots - gives it a 4 start. Still shopping for a small low priced camera that will take decent pictures indoors. For the price it’s a great camera for anyone.
Awesome!! 
I would recommend this camera to family and friends. My buddy talked me into getting a new one since I had a new baby on the way. I bought this camera with his advice and am very pleased. The image stabilization feature is perfect for low light when you don’t want to have the flash on.
Love it.
