T-Mobile USA offers landline over Hotspot@Home

I've been with T-Mobile for 5yrs. My wife and I use our cell phones for everything. I have a blackberry and she has a normal phone but is getting a blackberry or the new android phone. We don't have a land line and we don't have cable internet because we don't subscribe to cable tv. I pay for a verison wireless card for my internet on my laptop on the go. I want my phone to do it all. I want my phone to get the internet like my verison usb antenna. Then when i hop on my laptop i have the internet steaming from my phone to my laptop. And then when I get into my Ford F150 KingRanch my DVD/NAV screen in the truck hooks up with my phone for safe calling and safe google searchs, with a little three finger mouse at the edge of my center consul that allows me to move a cursor on my DVD/NAV screen with out having to touch the current touch screen with an uncomfortable lean forward while at a stop light, or in a parking lot as i figure out the next place i need to go in the city. Then when I don't have my laptop with me and I'm not in my vehical with that indash screen, I want to be able to seach the internet on my little blackberry screen. All of this happens with one bill. T-Mobile and everyone else needs to get their act together and stop this madness. Some people pay the phone company, vonage, cable company for tv and internet, cell phone company for wireless card, cell phone company for voice and text, and satilite radio in their cars, and now internet hotspots in their cars. Whats next? this sucks, too many bills. We need some drastic merging of technology. I can watch most tv on the internet now, and I can get my news on the internet also. And when I'm at home my phone internet should just display on my 52 in plasma. Please someone with a voice and decision making power, please help the consumer have a better option!
