If you have TMobile already, the service you should expect will be on the same level as what you already get. If you don't get a great signal now then you won't get one with the Sidekick.

I have one and I absolutely love it. It depends on your lifestyle though. I'm always out at loud clubs or bars trying talk to people and organize things, and the Sidekick is great for txting. I use it to check my email all the time and I do use the internet pretty often. Mostly I use the internet at a 411/mobile Mapquest but a lot of my internet use comes while I'm taking a dump in a strange place and have nothing to read.
