I just posted a review of the vaja case in this forum.
The seidio I found to be the case with the lowest profile - but note this was for the original iphone - I have no experience of their 3G/3GS cases.
I have found that both the incase slider and the seidio and I imagine any of that style of case can indirectly scratch the phone - it is the build up of dirt along the edges that works its way into the case - means when you slide the case off it has the potential to scrape mine did anyway - Not badly but it can leave marks.

How did you like the Seidio case? I ordered the pink one last night. Did it scratch your phone?
