There is a big fuss over the 3100, D5000 and D90, much is centered on the rear screen . . . ?
The D5000 is essentially a D90, with a 2.7" animated rear screen at 230,000 pixels, and no in body focus motor.
The D90 has a rear 3" screen at 920,000 pixels, it also has a
pentaprism OVF, larger and brighter than the Pentamirror in the D5000 and D3100, it
has the focus motor, giving more flexabuility to some?
The D3100 has a 3" rear screen but still at 230,000 pixels, and agin no focus motor.
You dont have to be to clever to work out, the D90 has the superior viewing apparatus.
The animated screen on the D5000 is a useful extra . . . I thought . . . however to use it, you need to switch to live view, its so slow to focus, I am finding it frustrating. I choose my G1 because of the superior focusing in 'live view' on the animated rear screen.
The D5000 is a great camera, but the D90 has the edge on handling if you dont need the animated screen. That also goes for the D3100, reading the spec., it is up to the D5000 without an animated screen.
To my mind this leaves the D5000 out on a limb . . . :shrug: I'm waiting for the 7000, see how it fairs in the first few months? There's going to be a lot of used D90's available, or does one stretch for a D7000 . . . I dont need the video . . . :bang:
The alternative . . . stick to just the G1 . . . answer the question truthfully; 'do I really need a DSLR' . . .
