And it did in fact kill the iphone that was current at the time.
Really? How so?
"As compared to first month sales of the iPhone() (about 600,000) and the Droid (about 525,000), sales of the Nexus One do appear to be moving along rather slowly. Still Sluggish: Only 80,000
Following disappointing sales, Google had already closed the Nexus One web store two months ago, so this final nail in the coffin was already overdue."
Thus, it’s no surprise that the phone has been discontinued and hardly anyone noticed.
