The only issue I've had with my N9 is it doesn't always talk to my router. Which is solved my rebooting the router.

Apart from that it is the best PHONE I've ever had - my N900 gave too many headaches on a day to day basis as a phone. As a tablet it still gets use at home.

I'm on my 2nd N9, as I broke the screen recently (alcohol related shenanigans) and found a 64gb in a store! ($400 AUD). I could have had any phone, yet still only wanted an N9.
