don't the images online and in the purchasing websites already show what it looks like?
it's pretty simple, IMO; it's just a stand, that lets you easily slide a charger in and out of your phone, that keeps it elevated and invokes the mm app. there isn't anything "special" about the mm dock...
however, for around $20 (after discount), it's lightyears better than the stands i've bought for other phones that do about the same thing. it's stylish, has a nice weight to it and the rubber strips on the bottom prevent it from moving.
i'd say, if you were to do one, to provide as many details as you can, like weight, images of the grips, fit of the phone, etc.
and to make it worth while, see if some of these other dock manufs would provide you with a sample to do a side-by-side.
...now there's something i'd like to see.
get ahold of every dock you can find, including the lego and cardboard solutions, and write a blurb on each one. benefits, etc.
i think that will REALLY help people.
