Another writer whose opinions I trust is Rita el-Khoury and here she reflects back on four months with the Sony Ericsson Satio and on the imminent arrival of the new Vivaz. She writes about the evolution of Sony Ericsson's take on S60 5th Edition and Symbian - it seems that she too sees the Satio as a testbed handset (as I'd argue are Nokia's N97 classic, N900 and Samsung's i8910 HD) with the Vivaz being the one that will make an impact on the market.
