Renee,
I've never used one nor do I know anyone that has. I looked at the specs however and it seems on paper to be a decent camera if all you want to do is point the camera at something and push the button (point and shoot). The only possible drawbacks that I noticed were the use of 2AA batteries and the use of SD cards. The 2AA's probably wouldn't last long if you plan on using the LCD to compose shots and/or use much flash. SD cards are just a personal dislike of mine like the Sony memory stick. I think they along with the memory stick will eventually be a thing of the past as most manufacturers are going with Compact Flash as a storage option. Even the highly touted Sony 828 that will be coming out within the next few days will now accept Compact Flash (Sony has seen the light).
As for your "why so cheap" question. I would venture to guess that Gateway doesn't have a big enough name in the digital camera market to demand the same prices as say a Canon, Nikon or Sony. This doesn't mean it's a bad camera, just a fact of capitalism. Another reason is that as you add more features to a camera such as more user options, ability to add adaptors, hot shoe, etc., the price will go up. As per the specs of your camera in question, it's mainly just a point and shoot camera without much expansion options (no hot shoe, available adaptors, etc.) It is still a four MP camera however and given that it's "in-camera" image processing abilities are up to par and a decent lens, it should still make some fine photos. Hope this helps your decision. Another option is to post your question on a digital camera dedicated site such as www.dpreview.com. Since you say its Fuji Built, I've added the link to the Fuji forums for your convenience. Have fun and Merry Christmas.
