The Nikon Coolpix 990 was a top of the line digital camera....over 4 years ago though.

Honestly, I dislike the design (physically) and the fact that it's 4 years old. (When it debuted, I don't know what the manufacture date is of when hers was made)
What type of a digicam are you really looking for anyway? Point and click? Do you like taking a lot of outdoor/activity shots? Nature? Wide/closeup shots? Do you like fiddling with manual settings? This seems like more of an older power-user camera.
Also - a 16MB card will hold very few shots on it in this day and age, especially at a higher resolution.
My recommendation is regardless, you could probably find a better camera for point and click for about the same money. (Canon A70/75, maybe the A80) A competing Nikon to the A80 might be the 4200/4300 series.
If you're really big into the manual settings, you might go with a DSLR, but that's well and above the price level of any of the above mentioned cameras.
