Google Phone: Nexus One / T-Mobile?

[stopthekilling77]

Well my faithful if not bulletproof, three year old Motorola SLVR L7 is going to be retired within the next few days/weeks.
My boss has a Droid, and my coworkers either have Blackberries or G1s. Having seen the Nokia N9000 up close and seeing all it could do that my phone couldn't do, I decided that I want something new like NOW.
The nice thing is that my company will reimburse me $20 for each monthly statement we bring in, as our jobs require us to keep ourselves available.
I like everything I see on the official site but I hear that Verizon is planning on neutering the software capabilities of the phone.
Having been an Cingular/AT&T customer for 6+ years I'm feeling the itch for something different, but I don't want to get shafted on having to deal with a neutered superphone.
I hear that T-Mobile is a decent provider, so I ask those of you who have been or are current customers of T-Mobile, please provide me with some feedback on their coverage, data speeds, issues, etc.
Any and all insight would be fantastic! If the company is decent then I'll be signing up to get the Nexus One for $179 with contract as soon as possible.
The SLVR is on its last legs, and I need a decision soon because I never know if its going to have a bad day

Thanks all!
