I think the comment is excluding now defunct Home Brew solutions that handset makers used to make on their own. However, those too probably were based on something else.
Even IOS, Android, Windows Mobile... are all desktop operating systems that have been modified, not TRULY built from scratch. IOS has done the best job. Androids biggest pitfall is that the user is basically running a program on top of Linux. (Yes, I know, it's more technical than that, for for laymens sake I say that).
IOS was almost a Linux based product as well, which most people hear have most likely read that story.
I think this is the best thing for WebOS.
It suffered from 2 problems:
1. Awful hardware (under both HP and Palm(
2. No developer support
This would fix both those issues pretty quickly if other manufactures jump on board, and with Google getting into the hardware business, many companies have been rumored to be looking at alternatives to Android now.
HP even has a win in this. By hanging on to WebOS in part, it positions them to be the gate keeper of an echo system ala Apple or Google, raking in a commission on what's sold and giving a steady revenue stream.
Its the echo system that makes the money, not so much the hardware. Device makers have done well with Android because what they save in in house costs on developing software makes up for the difference and has helped them get more market share.
I'm excited about this. WebOS I always did like... I just hated the hardware and there was nothing for the platform I wanted besides Facebook and few other must haves.
You need to start writing better fiction, and what the heck is an "echo system?"
