My wife has a Galaxy S phone. It has the best screen (IMO) on any phone including the new iPhone. It is fast and in general is a great phone.
However, the GPS does not work right. The Samsung fix did not correct it. My wife does not care but it would drive me crazy.
When I’m in the market for a smart phone I’ll get a Samsung. You know that Samsung is in the LCD business? They make them so of course their display will be superior to whatever the Taiwanese cook up for Apple to sell.
