While there were a few excellent Android phones released over the last 2 years... there were also tons of stinkers.
Which phone does your wife have? Thinking back 2 years ago today... there were plenty of "meh" Android phones on the market.
Like I said in an earlier comment... Apple still thinks highly of the 3GS they were selling over 2 years ago. So much so that they still sell it new today.
Can you imagine if some early-2010 Android phones were still sold as new...
