While not much practical use to our readers, it's nice to see Microsoft's Metro UI catching on in a big way. A new iPhone Twitter app called 'Maha' is an exact clone of some of the popular Twitter apps on Windows Phone 7 that adhere to the Metro theme e.g. Twitter (official), Rowi and Twitt.
Between what's been shown of Windows 8, Windows Phone and Xbox 360, this Metro thing seems to be catching on. Hey, imitation is the sincerest form of flattery. And maybe, just maybe, a few iPhoners will want a phone with the whole Metro UI.
