Did you throw Qt in there just to eliminate Android and the G1? :-)

Doesn't run RIM, iPhone, or WinMo? check.
Has a touch screen? check.
will run Qt? (does Symbian have Qt yet? I didn't think it did)
Open platform? as open as Symbian, so check.

And, frankly, I don't care about Qt compatibility :-}

It's a nice step for Nokia, but it's still not what I want.

Better keyboard layout*, Maemo, T-Mobile USA 3G, Dalvik. While retaining S60's tethering features (for use with my netbook). Those are what I'd want added on to this device, in order for it to impress me.

(* I question using that keyboard for Maemo's linux layer, or even for SSH on S60; and I hope it has a feel more like the E71 and less like the N810)
