I have the 8700 and have had similar issues. The main problem is when you switch to macro and you're shooting indoors without proper lighting, you are stuck with a very, very long shutter speed. Holding your hands steady for 1/2 a second is harder than it looks, and holding them steady for a full second is even harder, but unfortunately, without adequate lighting, the camera needs that much time to expose the photo properly.
Recommendations? A good monopod or tripod. This doesn't allow you to have one hand free, and it doesn't allow you much in the way of roaming the house capabilities, but it does allow the camera to be steadier/steadiest when the shutterspeed is so slow.

It really is a good camera, though. It just takes patience and stuff. It's not your typical point and shoot, although it offers many of the same features. It's almost like a crossover between a p&s and a DSLR.
