This is probably the main thing that causes more difficulty with an SLR than a 
compact.  Because the depth of field is so much smaller, if the focus is a 
little bit out, it matters uch more.
Apart from that, the main problem as I see it is that lenses for SLRs of 
equivalent length and speed to those available with the ultra zoom compacts are 
big and expensive.  Many people seem to opt for a 300mm lens to start with, and 
I think these struggle a bit to beat the image quality of a good compact in 
many cases (e.g. bird not close, and reasonable light).
