Like many others, I've come to learn a little too late how bad the camera is.
My story:
My wife has a document and wants the text from the document posted on a website. She says, "I'm too lazy to retype all of this. Does your new Surface toy have any solutions?" and I'm like, "Yeah babe, my Surface can do ANYTHING! I'll just snap a pic of the pages and use OneNote's OCR to convert everything to text!!"
So then I hold the Surface over the document (which is in size 12 Arial font) and I can't get it to focus. Thought maybe I needed more light so I went to the most well-lit room in the house. Same problem. Everything was blurry and no matter how much I tried, the best I could do was to get half of the document into focus. Everything else was too blurry for OneNote to perform the OCR on.
Feeling humiliated, I just typed out the document for her.
Sidenote: Before resorting to typing, I even tried taking a picture with my iPhone (which focused well and gave great resolution) and saving it into a OneNote document. Not sure what was going on that day, but my OneNote wouldn't sync for some reason and the picture wouldn't upload to OneDrive. Really weird day.
Am I disappointed? Yes. Do I hate my SP3 now? No... I still like it and I still think it's leaps and bounds better than an iPad. But as others have said, for the $$$ I dropped on this thing, it should have a auto-focus on the camera. My iPhone has spoiled me in this regard.
