Samsung's WIndows Phone 7.5-powered Focus S and Focus Flash are due to launch on AT&T this weekend, and to that note, the phone maker invited us to their office this week to get an another look at both devices (we previously had a glimpse during the Asia D conference). In our brief time with the 4.3-inch Focus, it hummed along quite snappy. Despite the bigger frame, it's both thinner and lighter than AT&T's gold standard iPhone 4S. We'll have more to say on the smaller and more aggressively priced ($49.99 on contract) Focus Flash in a review shortly. For now, enjoy the pictures below — and if you're so inclined, we've whipped up this handy comparison of Focus S and Focus Flash against its eponymous predecessor!
