What a snark-tastic post!
The battery has nothing to do with the viewfinder of an SLR....
gkarris, if you were up to speed on current dSLRs you would know that's not true. More advanced models have started using LCD overlays instead of swapping out focusing screens to get different focus points, grids, etc. Do yourself a favor, don't play an "intarwebz expert" on TV.
and you have a D90 - have you been using SLR's? The only first-timers I know that buy these are rich Soccer Dads and just use "auto".
Rich soccer dads either buy the D3000/D5000 or the really rich ones buy the D700 models. Regardless, nobody understood this stuff from the womb, the smart ones make the effort to learn the underlying principles instead of looking down their noses at people who are in the same place they used to be (but won't admit it).
To the OP, the D90 is a GREAT entry level dSLR from a value (features vs. price) perspective. Enjoy it! Get one of the D90 field guide books and a copy of "Understanding Exposure" to re-read every other month until it clicks (i.e. you understand the relationship between ISO, aperture and shutter speed and when to choose what).
FWIW, I wish I'd had the foresight to buy into the Nikon system when I went digital. Unfortunately, by default I went with Canon who seem to be more interested in megapixels vs. image quality and low noise. Switching now will cost me a small fortune. IMO, you chose well. Ignore the arses on the Intarwebz and go shoot some pictures.
