so it's basically a third party UI just like SPB shell viz for mobile phones. requirements are 720p display and honeycomb, not that much I guess. would have been quite amazing if mobile manufacturers were bothered about the reviews they get on their work like touchwiz.
i guess they would eventually launch a beta. no one likes to pay for an app without testing it out first. in any case, this is the type of app that would need a couple of days of usage before you can decide if it works for you. i mean i never got used to any third party launcher. largely because i did not give them enough time.
