You have missed out lens. No point getting D-SLR unless your going to change lens. They are big clumsy lumps now too big to have Eveready cases and unless you intend to change the lens why carry around an advert to mug me I'm rich device?
OK there are other advantages but so much of the cost of an SLR hinges around to ability to change the lens.

To me the big problem is a D-SLR has a 18-55mm lens and the compact has a 10x lens and it is not easy to compare. √(18²x10) = 56.921 so the two lenses do about same zoom but since 10x does not give starting point not a direct comparison but the compact as name implies is smaller.

Yes the CCD on a D-SLR is likely bigger and it likely can take pictures in RAW and has built in histogram to tell you have your doing. However that then takes one to next level is computer software and to read RAW files either you use the bundled software and have to know how to do tone mapping or buy something like Photoshop CS4.

I have spent the last 6 months 5 hours a week learning how to use my D-SLR and I love it. Best thing I could have done and I really enjoy the hobby. However unless you are willing to spend the time to learn how to use the camera then its a lot of money for very little gain.

I use a slide copier, bellows, 400mm fixed lens, and reversing rings and to use all these one needs to be able to remove the lens. But I see nothing on your list which needs one to remove the lens to use.

Not trying to put you off, as I say I love my D-SLR but do consider if it's the best option for you?
