My biggest expectation for mobile device is some device running open source OS and have no limitation for OS upgraded and driver open.

The closest OS is Mer and it almost already succeed except ARM CPU manufacturer refuse to provide open source driver.

Why Mer wait for special manufacturer? There are many manufacturers for same level ARM CPU. Some hope to keep sth secret for high profit but this choice shouldn't be the only choice of all manufacturers.

After Mer have been success on one platform then more hardware manufacturer will choose to compatible with Mer otherwise they will lose a big market.

All user who have suffered from 18 month support then be abandoned and forced to buy new device should push independent mobile OS.

Mer should find the best way to success and not just wait for sth happen.

Mer perhaps doesn't have same goal with one ARM cpu manufacturer but independent OS shouldn't depend on any one. It should be the leader of this history trend.
