I agree. After the debacle with HP and the Pre3/webOS 3, I wouldn't put any faith in all these pie in the sky alternatives. All of them so far have either released fancy videos or a simulator/sdk, but none have come anywhere close to a 1.0 release. Meanwhile the Android juggernaut rolls on....even Microsoft can't seem to make a dent with Windowsphone. The longer these alternatives take, the more iOS and Android cement their current users further into their ecosystems

(And unless the carriers support it, the hardware manufacturers are less likely to release phones based on a particular OS or release the vital code to make an alternative OS work with their phones.)
