The dutch market is looking forward to it! We just had an amazing Android dev camp(www.androiddevcamp.nl) in Amsterdam with 250 people attending. The belief in the platform is increasing compared to half a year ago. Not sure how sales of the device will be.
Personally I am using the G1 since begin November and it is the first time since the N6600 that I don't use a symbian device... That says alot.. Very happy!

Poland here, I can't afford getting one (rather tight student budget, plus I'd rather go for S60 or even WinMo Pro), though I can check the pre-launch hype and the launch itself. I'm not sure about the phone's name here though - we still have Era instead of T-mobile, though rebranding's supposed to happen soon.
