Your strategy didn't move many units for Openmoko, Neo FreeRunner, N900, etc. Why will it start working now? The Vivaldi tablet running KDE Plasma Active is supposedly shipping soon, did you order one?
People's expectation for a phone/tablet have gone up. They expect a consistent touch UI which is only now starting to appear in Linux toolkits and will take a while to come to native Linux apps. They expect maps and navigation, calendar & contacts sync, device sync, an app store, which all require hefty investments in online infrastructure, or Google to provide it for your platform. It's daunting to compete, HP and Nokia decided they couldn't.
The only realistic hope of > 1% market share for "old-school" (not-Android) Linux on phones and tablets is if most apps are written in HTML5 as Tizen encourages. Then the platform matters less, and people can switch, the same way a desktop user surfing Facebook and Gmail plus doing some light document creation can switch to a Linux distro. Yet I mostly see old-school Linux users belittling HTML5 and insisting web apps will never happen. Fair enough; so long as enough developers are motivated to work on projects like Mer then users will be able to install Meego/Maemo/Plasma Active/Tizen on their phones and tablets, just like the few who install Linux on their desktops. But very very few will do so.
