Apple is whatever it is because of its long story in taking unorthodox choices and consequent revolutions.
Which means a lot of work, a lot of betting and a bunch of wins.
What I've seen so far is changing a default color schema, a "new" font and a new naming schema.
Not even the "new" desktop is really new as
Unity is a shell interface for the GNOME desktop environment
(Very first line in Wikipedia)
Ubuntu, like Unity, is a shell around something else (Debian) with very limited value added.
Just "going to the clouds" (tm) doesn't make a winning company (alo because everyone else is going there).
No, I don't think Canonical will be the next Apple (or even Microsoft). It's more likely it will be the next Mandrakesoft.
