Attention Marketing: I have a way for you to determine if a product is going to flop or be hot. Go to some customer sites, techie conventions, give away a bunch of T-shirts with future logos on them. One per customer, and have them vote with the swag.
I have been going though this because some partners and competitors have been giving shirts to my customer. Of course, they then look at me, "where's Microsoft's shirts?". I decided to take some quick polls as to what type of logos they would want on a t-shirt.
So, I am now looking at what our options are to get Xbox 360 shirts.
