I've got the N6280, I think it's great. Reception is excellent, much better than my old T610, the camera is vastly better. To say it's got 2Mpix is a complete lie though; 1600 rez is no better/sharper than 1280, so I take pics in that mode and save a lot on storage. As already mentioned there's no AF, and it can't focus clearly any closer than ~25cm. That's a bit of a bummer unfortunately. Daylight sensitivity is pretty good unless there's a lot of contrast in the image, but low-light performance is crap; when lighting gets dull (such as dusk) you can get banding in the image, and when it's dark there's blue and red color speckles galore. LED light is VERY bright, it makes a noticeable difference up to about 2m away, and perhaps more. Unfortunately there is no option for it to come on automatically. It's generally not enough to remove the speckles though, and activating night-time mode just makes it even worse. You'll get a speckly AND washed-out image...
Bluetooth transfers are fairly quick, no slower than USB transfers it feels like, so the storage speed is probably more limited by flash access speed than wireless transfers. Media player is a bit cumbersome, it won't look on the memory card by default for songs to play, you have to tell it yourself where you stored the stuff even though there's a premade folder for music on the card.
Just don't drop it on the floor though; the sliding design is likely to pop apart if you do, and like humpty dumpty you might not get it back together yourself again...
Also, don't leave the phone plugged in thru USB for a long time without the charger connected as well; that'll eat the battery like crazy.
On the whole, a great phone IMO with everything you need. Pretty much zero flash built-in, but 2GB storage slot is plenty. Images at 1280 generally get no larger than ~950K, and typically considerably less, so it'd take ages to fill a memcard of that size. Even the default one (64MB) can hold at least 150 shots and probably a lot more. Too small for music tho, but flash is cheap today. Just run out and buy a bigger card.
