Nervous about Nikon Coolpix 5700 purchase

[Raedeke]

We have owned a Canon Digital Camera for about 6 or 7 years. My wife is very much into her Canon AE-1. And we are in need of a new digital camera. So I bought her a Nikon Coolpix 5700 thinking that she could still enjoy the great features of her SLR, but in a digital format.

Was looking at a Canon A80 or the S1 IS, but ended up with the Nikon.... Didn't do my home work on that unit and when I got home I was concerned to read about all the troubles people were having. Specifically with the lens gears and the low light AF.

Should I return this thing and reconsider my purchase or are these troubles from a handfull of individuals?

Would love some opinions of the subject.
My wife will probably never give up her AE-1 and rightly so, but I'd like to have something that's a bit better than a standard point and shoot digital and love the 5MPix on the Nikon - any suggestions...

Thanks so much.
