Well Ian, I "converted" completely from Pentax SLRs, with the equivilent load of lenses etc, to go completely digital.
I purchased a Fuji 4900 zoom which I have found more than adequate for my use. I tend to use my images for websites, so the convenience is one thing I was looking for, and you cannot get much more convenient than publishing some of the photos on the websites within hours of taking them!
I also like the further convenience of the fact that the Fuji is a self contained unit with a 6X optical and 10X digital zoom, so it not only replaces the two old Pentax SLR bodies, but a multitude of extra lenses too.
This particular camera also has a TTL type viewfinder which previews the shot in the viewfinder so that you know instantly if the shot is any good or not.
With regard to the wide angle bit, it is not really necessary this day and age with the multitude of software capable of "stitching" images seamlessly together.
Obviously, if you want to display huge posters or prints, then the cost of the digital equivilent of the film versions capable of giving good enough quality would be prohibitive. If on the other hand, you want quick access to reasonable quality prints and futher wish to publish to web, then remember that as most monitors are only capable of displaying at 72dpi, then anything taken over that resolution is a complete waste!!
