From all the reviews I've read.....
The Titan seems like a better option overall, even the Focus S to-some-extent.
The unique "Nokia only" apps are no longer Nokia only...

So there's now zilch significant advantages (hw or sw-wise) that it has over either.
Unless you're one of those 'art farty' types that prefers form over function.
BQ of both is solid, their cellular reception might not be quite as good as the L800's.
But the differences probably won't be noticeable in RW terms.

There's heaps of apps, & growing by the day....
Whether there's enough or exactly what you want, depends on you the user.
If you're basing your assumption of 'lack of support' on the N900 experience, then you're mistaken.
You need to do a bit more reading about the N9, & what Nokia has said etc.

If after much more reading you still feel it's not for you...
One of the marquee Android devices is a 'no brainer': SGSII, SGNote, SGN, Droid Razr, Rezound, SGSIII (should be out Q1).
I'm personally waiting for more info about the SGSIII, I'll wait for a few more SGN reviews, but I don't think it's good enough.
Better than the Razr, maybe even slightly better overall than the Rezound (debatable), but not enough of a stand-out overall.

Even the iP4S is a very solid option....
Nokia WP's won't (may) be truly compelling till WP8x*, for now they're just 'scratching their arse'.
