I absolutely LOVE my Nikon DSLR. It's addictive, and very very easy... since it has a double auto feature... so you can have the lens on auto focus, and just twist it to zoom... as well as the camera itself on auto. Or you can leave the lens on auto and use the different features (sports/kids/night/up close/distance/portrait/fireworks/museum/ etc.)
Then, when you're feeling adventurous (and since it's digital, you aren't wasting money learning) you can put the lens OR the camera OR both on manual and start learning focus.. or aperture/shutter speed/etc.
The DSLR's also "last" longer than pocket digital cameras... because you have the lens to zoom with (and they're built super sturdy to begin with). Just as an example... my DSLR is only a meager 6.1 megapixels. BUT because of the lens (and I've gotten hooked, so I have a few lenses now), even just the original lens... my 6.1 megapixel camera takes better, more detail heavy pics, than my Mum's 13 megapixel pocket camera.
Right now, I'm waiting for the 24.5 megapixel camera drops into the $600-800 range (probably in about 2 more years) before I upgrade my camera body. If I had the money I would get the 12.5 body now... but I'm certainly not heartbroken about it, because I have my lenses, so I can wait. Same token... any lenses I buy... snap right into any new body I buy.
Even when I upgrade though (and I have 2 friends with $ to burn, and one prof. photographer friend who DO have the DX3 24.5 megapixel camera... I'm still going to keep my old D40. It's water photos (out of water... not under) are simply phenomenal... and it's "kid" setting really gets kids true skintone, which is super rare for auto. There are a few other things about it I love, too, and I have lifetime repair on it... so when I have a fancier-schmancier one, I can still have a backup for the rough and tumble stuff.
That's another thing I love about DSLRs... everyone I know who has 2 or more KEEPS their old one, and uses it still. Both for features they love, and as a backup that still takes GREAT pics.
DO buy the multiple year or lifetime repair warranty though... I've had to use mine twice (dropped it once, and my toddler spilled OJ on it another time). Got it back a few weeks later. Good as new.
LOVE Nikon's digital SLR's.
