Also, one thing that was the most dissappointing, the transfer rate. It was dog slow. My W810i came with a 1 GB memory stick and it felt like an eternity to put some music on it. I found out by doing some searching that the internal transfer rate is much slower then USB. My iPod and PSP can transfer a song in seconds, this takes multiple minutes.
The phone was not terrible, but I was severely dissppointed for it's cost and advertised feature set.
When I mention the cables, I mean they are all proprietary. You can't use just a plain old headphone in to the phone, you have to use the dongle. Also, the USB cable is proprietary, so if you damage/lose the USB cable you can only replace it through whoever sells the accessories for this phone and it's expensive (you can't just go to staples and buy a new USB cable for cheap).
About the navigation, like I said, I probably didn't have it long enough to learn and get used to it. It was very minor gripe.
Those are my beefs with the phone. It was a cool phone, but since I was so dissappointed with the transfer rate and all the shitty cables, I returned it and got a crummier (and cheaper) razr until a true all-in-one solution is available.
just my thoughts, others may not be bothered by them.
