The Hardware 2.0 Blog posted some thoughts on the Windows Phone 7 technical preview

After all, the smartphone market is a highly competitive arena, and the best way to do that is to have that one, must have killer feature. Then, the rest of your product doesn’t have to stand head and shoulders above the crowd. Consumers can then assume that product A is similar to product B, except that Product A has Killer feature X and product B has killer feature Z.
