Well I'm very much a beginner, so anyone can correct me if I'm wrong with any of this information.
Yes, its a coolpix 2500 Nikon. You may find it hard to locate one of these though. They've almost pulled them out of the market and substituted them with the Coolpix 2100. The features between the two cameras are almost the identical. The only thing I don't like about the 2100 is the menu system. The 2500 carries the same menu system as the 4100 if I'm not mistaken. Its like an overlay to your viewfinder. You can still see things in the background. When you enter the menu on a 2100 it takes up the full viewfinder. Kinda like the dummy version if I had to sum it up in two words. Mind you, all the same features are there and its a great, I just don't like the menus. The Nikon comes with some 'scene' settings that include close-up(macro). It also has settings for sunsets, fireworks, museum and all that jaz. You can use them, or you can set everything manually, which I find myself doing more and more.
I'm no camera professional, but if your looking for a camera I would keep a few things in mind. Look for optical zoom over digital zoom. The coolpix has a 3x optical and a 4x digital, which makes for a pretty good zoom. I never use my digital zoom for fear of picture degradation. Some cameras only have digital zoom and I would stay away from them. Also make sure you look for the word macro in the camera descriptions. If you don't like Nikon the Fuji Finepix 2650 has macro capabilities as well. I've looked over a few kodaks and was unable to find one in the 2mp range that had this. The Sony 2mp also looks unimpressive, and it uses sony's own proprietary memory sticks. Don't forget batteries. Don't buy a camera that doesn't come with a rechargeable lithium ion battery and charger. I know some of the cheaper cameras don't come with them, then you have to go buy rechargeables and all that jaz.. its not worth it.
My advice would be research. Find a few that have everything you want, read reviews.. multiple reviews, then go to the store and play with them. Make sure you like the menu, and the hands on feel of the camera in question. It looks to me like the Canon Powershot 2.0, Fuji 2650, and Nikon 2100/2500 all have macro capabilities.
