I too have thankfully not experienced any of these problems. So far from my usage the N900 has been very impressive. However, I have yet to fully delve into the device (been busy with finals). I have been using it as my primary device though, and it has performed admirably. There have been some very minor issues, but nothing major enough to even register as an afterthought in my mind. I am using Tmo's even more plus plan, and I have been on 3G and 3.5G speeds most of the time. I will post my thoughts in the first impressions thread after further usage, hopefully by the end of the week.
