Upload & Sell: On
Yes, you can upload them to your computer. And, if you haven't used a modern smartphone camera, they're actually pretty good. They're obviously not going to best a DSLR or something, but they are easily as good (or better) than most point and shoots from a few years ago, and even better than some of the modern cheap P&S cameras. Obviously, a high end compact like the Sony RX100 or Fuji X10 or X20 is going to be a lot better than a smartphone camera, but most people don't really care that much. The average person doesn't care one lick about noise or dynamic range. They want to be able to get a decent shot to upload to Facebook or Twitter.
I actually don't own a compact camera any more, and I use my iPhone when I want to take some quick pictures and don't want to carry a camera around. While my iPhone photos make up a very small percentage of my total shooting, I still take about 2-3,000 photos with my phone every year. In good light, I can print iPhone pics up to 8x10 and they look great. I actually made a little montage print of five Hipstamatic shots I took at my college when I was up there in 2011 for my 10th reunion. I took a ton more shots with my main camera, but the iPhone shots were consistent in processing and I liked the way they looked. I just had them printed as 5x5 prints and they look great on the wall.
