LG Quantum Windows Phone 7 looks more like a feature phone and it has the smallest screen in the early Windows Phone 7 handsets . However, it offers the super responsive QWERTY keyboard that some users can’t live without and is a solid bet. While it looks less like a current generation smartphone and more like a feature messaging phone for the tween set, it meets Windows Phone 7's smartphone standard specs with a 1 GHz processor and 256 MB RAM.
