Looking forward to see if some hardware manufactures bites this bullet and produces some useful open devices. To me, webOS seems to be the most open OS and realistic alternative for mobile/tablet devices. Android really needs a competitor.
maemo->MeeGo->Tizen looks more like /dev/zero (yes, zero) to me. I actually expect Tizen to change name again some time later this year when somebody are able to announce a Tizen based device. It steps back to start over and over again, with zero progress. After all that's what happened before Nokia N9 (and N950) was announced - and abandoned before the hardware was really publicly available (iirc). And MeeGo was announced shortly after N900 with maemo5 was publicly available, after talking loudly about how great maemo6 would be. Did these decision makers ever hear about the Osborne effect?
