According to this article:
More to the point, however, is that we can’t really trust early reviews. I always recommend caution when it comes to buying products that have just launched and I rarely take my own advice. Many devices only begin to exhibit problems after lots of use and many faulty devices pop up only after the first batch of highly scrutinized devices runs out.
In the end, the real reviews are the ones that percolate up out of the forums and blogosphere.
So, what are my thoughts on this?
