nokia had meego but microsoft went and bought them and fukked them up. As much as i like android, there have been a number of mobile operating systems still used by consumers today.. imagine if WebOS and meego had a chance to mature. windows mobile was so locked down, devs didn't bother making anything for it. microsoft wanted the walled garden apple business model for their customers so badly they kneecapped their own OS. couldn't even export your contacts without it being a hassle. either you had a microsoft account to sync it too or you have to email it in a non standard format. microsoft basically wanted devs to make web apps while android was providing them with a deep API to do all sorts of things. 3rd party rom development really made android what it is today. companies saw what power users were vying for.
microsoft gave up to early though. they should make another OS, borrow from android + ios and add in their own functionality. they could copy googles mobile strategy, open source OS with proprietary apps. i'm not a propenent of proprietary apps but it's still a lane they can take.
