Just to clarify, a router is not a car. To make the same comparison is a 625 would be a 2007 model and a 626 would be a 2008. I'm not sure where the revisions would fall in the comparison (The 625a is a Monday morning model and the 625c is a Wednesday or Thursday?)
So lets forget comparing the the auto industry, OK?
Anyway, all I see here is D-Link made a mistake with the revision A and won't admit to it. They came out with the revision C to fix this and have been making updates to it all the time. I plan on replacing my revision "A" and you can bet it won't be a D-Link. As I said earlier, those of us who bought the revision A were early adopters, and D-Link has just forgotten about us.
BTW, us early adopters are also the ones who others listen to. i.e. I am the one who my friends run to when needing advice on computer purchases. D-Link just fell off my list of recommendations. Mostly because of the kinds of replies I see from them here.
Later, and I mean, much later,
