Same reason why people were upset about no dual core, or no HSPA+, or no SD slot. They just want the best technology out right now so they can say they're phone is the best there is, for about a few months till something better comes out. I dont get why people are throwing a fit over all these missing items. Im content with what they added to the nexus s from the galaxy s line, atleast the vibrant. I have a vibrant right now and i wish it had a front facing camera. Sure it sucks that the nexus s doesnt have HSPA+ but considering its a pure google phone, it makes sense that it wasnt added. If it was it would make it more of a T-Mobile phone than an open network phone. So that makes sense. Idk im surprised people weren't complaining it didnt have a flux capacitor
