Not really, the list could go on with for instance integrated skype (huge difference to separate app), a lot of great customizable widgets (no, the n9 doesn't have widgets because it probably wants to look as dull as the iSnore), the n900 is not locked from doing anything you want with it (in fact it is built with the intention to be modified) in opposite to the n9 where you need to go through a sort of rooting process.
I dont' see how the x11 support, customizability, stylus, stereo speakers (and 32 gb to a lower price) is debatable. its tnings that n9 completely lacks.

Further I would be cautious talking about the hardware in the n9 since it comes with a cpu that is even inferiour to the one release in the galaxy S years ago. comparing the gpu in the n8 also makes the n9 look pretty silly.

On top of all this the N9 is very expensive if you compare it with other smartphones in the same segment and with the same target customers. If you'd want such a phone you'd be better off with a Galaxy S II by far, unless all you want is to have monster glass, true multitasking and a more true to the design linux os.
Phones today is mostly about fanboyism and neat thick, slick design and apps apps apps. If you want something else beside this superficial fluff you're left with very few alternatives.
I had my hopes up for a long time with where Meego would end up, but when i saw and read the n9 specs it was a big yawn and disappointmen
