A bit of iOS's proportions, a bit of WebOS's textures, a bit of Android's color – yet they've managed to keep it looking clean and unified instead of middling or compromised. Outstanding indeed.
Maybe it's just me but the inital designs still feel iPhone/iPad centric. The UI/UX for webOS are more gesture-like and I do not see that reflected here as an alternative. However, it's a good start and it is heartening to see that Palm has signed up for this.
