Complete review over at The Wall Street Journal
Snippet:
More importantly, the N800’s software seems unpolished and unfinished. There’s no calendar application, no method for synchronizing data from a PC, no software for using the camera to record videos or snap still pictures, though Nokia says that’s coming. And there’s no simple way to use the camera for video conferencing with a PC, unless you get somebody else to download a special Nokia program. The company hopes to solve this later with a Skype program for the device.
I don’t like how he references the iPhone and uses it as a baseline comparison to the N800. Two totally different products. He does highlight a few issues however that are being echoed across the net: it needs to interact with your PC, the UI can use a bit of polishing, and most importantly the out of box experience needs to improve.
