New thoughts on a bridge camera, may be the way to go

I was just thinking that I have my Sigma 17-50 EX OS HSM on my new T1i, and I love that combo and would never get rid of it. But i also have a XSI 450D body in my bag with the Nifty 250 (55-250 IS), and I only use it outside when I go to the park and want to take bird shots or other wildlife that i need to zoom in on. I never use this indoors.

I was looking at outside and Macro shots with the Sony DSC-HX100V bridge camera, and I decided to look at reviews and other pics, and the thing seems to take fine qaulity pictures when outside in good lighting. It has 30X zoom, so Way Way more reach than my Nifty 250, and since I only use my 450D with that lens outside, wouldn't I be doing a good thing by selling my 450D and 55-250, add in my Nifty fifty since my Sigma handles that as well, get about $400 for them as a set and buy the Sony, or even the Cannon G model that has 36X zoom?

The extra reach gives you a lot of interesting pics, you can zoom right in on birds nests a long ways away. Just go to the Sony section here and typ in the HV100 and check out all the outside, good lighting pics, they are rich and colorful, detailed too. As it is now, I carry around two DSLR bodies and I am only using the 450D and 55-250 rarely. I went to the park last week, tried to take a pic of a duck and simply didn't have the reach. With the Cannon 36X zoom, I could reach out to the middle of the damn lake and fill the frame. I am just thinking that I would use the cannon or Sony with the great reach far more often than i use the 450D with the 55-250.

Of course i would still use my T1i and Sigma for important shots and all my indoors shooting and portraits, but it just seems like the bridge cam would give me more use outdoors, and it is smaller and lighter, no changing lenses, it just seems like that would be a smart move.

Any opinions on this?
