WebOS wasn’t tried in any meaningful sense. It was abandoned within less than a single product lifecycle by the various companies under which it operated. Windows Phone was an epic disaster in how badly it was rolled out. It was Ballmer at his worst. MS kept oscillating between whether they wanted Windows Phone to be an iPhone competitor or an Android competitor. They picked the worst of all worlds, by choosing to focus on distributing through 3rd party vendors, but refusing to allow them to make any changes to the interface, therefore basically eliminating any major vendors from adopting and promoting Windows Phone. It’s still amazing that MS was unable to unseat Android at a time OEMs were desperate for an Android alternative thanks to the uncertainty around the Oracle lawsuits (and were already paying more to MS than Google for Android! thanks to MS’s OS related patent portfolio). Ubuntu Phone never made any sense, targeting the most expensive niche of the market as it did.
