I'm trying to get a feel for how satisfied people are with Windows phones. I'm in the market for a new phone. I've been suffering for 3+ years with a Blackberry Pearl so it won't take much to improve my situation, but I really want the best possible phone I can buy. And I'm not willing to neglect Windows phones (just yet). My obvious first choices are the Samsung Galaxy S2 (although not available where I live) and of course the iPhone 4S. Currently the best Windows phone is the Samsung Focus.
<bot>: Should I buy a Windows 7 phone instead of an iPhone 4S or a Samsung Galaxy S (the S2 isn't available where I live).
