Why?
And who is to blame? If software publishers with proprietary applications saw Linux as lucrative, they would put more resources there.
This is a chicken-and-the-egg question that the Linux community needs to resolve if they want to gain meaningful market share. One reason Android became first viable, and then dominant in Smart Phone total units sold was the arrival of quality apps with mainstream consumer appeal. But until the Droid 1 gave Android a big enough market base to attract those developers, the platform was largely ignored by most top-tier publishers. GIMP and Open Office will *never* be those things for Linux.
Ubuntu needs to find their "Verizon"... someone who has something the competition doesn't have (the best network... Verizon,) but lacks something the competition DOES have (the most attractive smartphone platform - AT&T and Apple).
