AT&T to launch 3G services soon

Almost every major outlet has been reporting that on Tuesday AT&T will announce the launch of 3G services in 4 markets in the US. I have been an AT&T subscriber for 5 years now and I have been sooooo excited to ditch AT&T for another provider since my contract is now up. That is until I learned that one of the cities they will launch the 3G service in will be Seattle.... where I am moving to. I will now have to seriously consider if I should give AT&T another shot and try their 3G offering or ditch them and wait for Verizon or someone else to offer 3G in my market.
