Windows 6.1 is officially out, and after a hands on with the standard and professional versions of the refreshed OS, I'm still not sold on it. There's no denying the redesigned home screen is beautiful, and easily takes you to emails, texts and events for the day. But it still doesn't make up for the laggy nature of the OS and the menu surfing required to perform simple tasks.
Once you get past the homescreen, you're pretty much back to the same context menu-based system of navigation. The main difference between the Professional and Standard editions is that Professional is designed around a touchscreen and Standard is designed around a QWERTY Keyboard and soft keys. For the Professional edition I used an HTC Touch Dual and for Standard edition, I used an HTC S620 and a Moto Q9w.
