The featured phone is the same one I have and that I gave wife Barbara and daughters Kim and Xenia for Christmas. Barb explicitly told me not to get her one (after I had already bought it). But now she uses it all the time. She plays games on it, she listens to music with it, sends text messages, and she can even check the weather and make phone calls with it. She has thanked me repeatedly since Christmas for getting it for her even though she thought she wouldn’t like anything “too complicated”. It’s not complicated.
It is also the same one that son James and his fiancé Kelsey have. I evaluated all the Windows Phone 7 available just before Christmas and the Samsung Focus edged out all the others with it’s bright display, the camera, and the sound quality. Others apparently agree because from what I’m hearing it is a very, very popular phone.
Full disclosure—I work for Microsoft and I wrote some of the software that goes into this phone.
