Do you see any additional value in the Palm features of the iQue. This is a big plus of this product.
I have the iQue and it works great! Can't speak to the Street Pilot. The portability of the iQue is great. Voice directions work great.
I suspect they both use the same software so the actual features of GPS are probably the same.
