Craig Grannell making the point with a comparison to early iPad coverage:
I still like my iPad a lot and I don’t regret buying it, but it certainly doesn’t live up to the initial coverage online—and that’s something you only realise and can only tell after extended use, not through seeing a couple of pictures online and a keynote video.
Doesn’t matter who the person is, or what the device is — you cannot and should not review something that you have never used. Likewise I don’t recommend things that I haven’t used first. So the “Amazon Items of the Week” posts, yeah all those items are things I own, like, and therefore can recommend to you.
I have no problem with speculating on announced products, but calling such speculation a “review” or “buyers guide” is basically out right lying to your readership.
