Thanks so much for all your well thought out responses! I really, really appreciate it. You guys have given me many things to think about.
It looks like we will be shopping locally on Tuesday (birthday shopping, birthday lunch and then Avatar in IMAX 3D...all the day BEFORE my birthday!), so I have a few days to do some more research.
I had no idea that there were adapters for the lenses, so that is a huge plus. It opens up a whole world of possibilities for me! I really need to think about when my camera will get the most use to help me determine which type to get first (I agree that I'll eventually have to have both!). Most of my photo ops are occurring around our farm or on the bike. Since most of my biking is pretty casual, I could easily get away with carrying a DSLR with a 50mm lens in a handlebar bag and be covered. And of course, around home, size doesn't matter at all. I never go on vacation or travel (or rarely, anyway), so that's not really something I should worry about right now. Water resistance is probably somewhat of a concern, but I can work around it.
And yeah, I think POS was a slip of the keys! ;) But perhaps an appropriate one! ;)
