He is absolutely Right. In my case I have not a N900 but an N9. I won't take anything less. But my bets are for Tizen since it's an effort regulated by the Linux Fundation (No matter Intel & Samsung are paying the bills), so is the official Linux phone. On the other hand, well Ubuntu passed from the glory to the shame. Ubuntu is not open, is highly over populated with spam and SUCKS big time.
