I purchased my 920 based on the experience I had with the 900, which was very good. The 920 "as I've expressed previously" is a highly flawed device. Not only was WP8 not ready, the 920 itself lacks in overall quality. A part of this IMHO is do to Nokia moving manufacturing to China, at a time of uncertainty within Nokia as a company. I've had two 920's and both have design, QC and software issues. If I would have browsed these forums I would have kept the 900 and been happy.
The single biggest issue myself and others have had, is with the battery, which doesn't come close to my previous phone the 900. One other problem with the software is the corrupted video files when shooting 1080 video, if you actually want to watch the video you have to shoot in 720. The camera itself isn't what Nokia and some here say it is, in fact the lens flare is so bad it's unusable anywhere near a light source.
While many come here to simply complain, others are placed here for positive spin as well. So you have to read between the lines, filter out the hype, kids, idiots and the company people.
