So.....I think I have decided to keep the 5D.
Everything I looked at to replace it with involved compromises that I wasn't happy with. The 5D of course has it's own set of compromises that I am unhappy with too. (Size, weight, and cost!)
The current, and soon to be released crop of mirrorless interchangable lens cameras are still too big with anything but a pancake prime to be pocketable. They all don't have a built in flash or a remote shutter release, and I would want both. The Sony NEX5 would be my pick of the bunch. Comes with an external flash, and has a remote option. The lens options are limited currently, and the only pancake currently available is too wide for general purpose use. 3 more lenses coming out this year though.
The compacts mosltly don't support RAW or have no depth of field control.
Trading down to a 60D or 600D would save a little size and weight, but would mean changing all my lenses to get suitable focal lengths, which would probably not free up any money in the end.
So, I'm going to do 2 things:
1) Set myself a goal to post 1 new photo here every week to get myself using the gear I have.
2) Look at getting a compact take everywhere camera for snapshots.
