Shokinen, there's a bit of info you're missing about me.
I used to have an SLR back in the film days. Got it in 1990 and used it until 2003. Fully manual. Loved it! Shot way way way too much film.
In 2003, when I moved to Sri Lanka, I switched to digital P&S since my husband had one and film is so very relatively expensive here. My current P&S is great for a P&S, but I totally notice the deficiencies in terms of not being able to do anything manually, which is at the point of just irritating the heck out of me. And knowing that I can focus manually faster than this camera can doesn't help.
For my own sanity, I need a DSLR, and I do tend to do a fair bit of manual so I can get the shot the way I want. I just haven't been in a position financially to get a DSLR prior to now.
I've read up a fair bit on the D5000 vs. D90. and really, the D5000 isn't enough for me. The D90 is. And it'll be enough camera for me until I need to get a better, faster, more powerful one in 5 to 10.
Which really means that I suspect my mind is pretty close to being made up if it isn't already there.
