I was somewhere between Minor Niggles and Serious Doubts but chose Serious Doubts.

Major gripes:
- Power management on my device is completely erratic (sometimes I get two days, sometimes just a couple of hours with similar use),
- Some core apps should have been ALOT better even as an initial release (Mail client and Maps are terrible and really detract from the usability of an otherwise excellent platform)
- Development tools, APIs, and documentation are completely unorganized in my opinion which is very frustrating from a developers point of view (not even mentioning the divide between GTK and the half baked Qt implementation) That combined with the relatively small target audience will keep the top mobile development mind share away.
- OVI store still not up and running (and even when it gets up and running, what can we expect in terms of content)
- Minor things such as: no support for N900 in OVI suite (I mean come on!!!)

I still LIKE the device, mostly for the potential it has, but unless these (mostly) software issues are resolved quickly, I am very concerned about the future of this platform.
