Fair points rhett. Basically, don't buy a camera as a penis extension, buy it to take photos. I get imaginative shots using a Ricoh compact. It is the man first, machine second. Never imagine that an enormous lens and camera will make you good.
In summary; the 5D is more consumerish, 7D more 'pro'. Each is capable of things the other can't do, depends what you hold in higher regard
Now for the waffle!
To me, the 7D emerged and needed a serious firmware. To me that made it seem unfinished, unpolished, rushed out becuase Km were really getting behind - and now they're dead. (sound the trumpets) There were several 7D quality control issues, more than the 5D, which came out seeming finished and with far fewer problems of any note.
The 5D's ISO selection is cleaner, easier, low and high key is right there in front of you, instead of buried away under the ISO BUTTON after CHANGING what the iso button does in custom functions. Good lord! If you don't do low-key/high-key that's fine. But it works.
The 5D allows you to zoom in on RAW files, so you don't need matching jpegs. That's something the 7D lacks... more modern? In that regard, yes. More advanced then? Maybe, it is actually capable of getting all the photos the 7D gets after all.
BUT... and it's a big old but... the 5D controls and lcd let it down for me. It wasn't always quick enough off the mark. The 5D lacks dials. The Function button idea is so lame - because too much is crammed under one little button. Slow. Slower than the D70, which is saying something, as that's irritating too.
The 7D is, for me, better than everything except the D200 and 5D and so on - but these are the next level, the next generation. If the 7D had a bigger, more powerful ccd and 5fps, (and as rhett says a nicer, gasket filled body to keep out dust and splashes) then the D200 wouldn't get a second look from me.
I'm happy with the 7D. For now...
