There is a general perception that HTC Dream aka T-Mobile G1, the first phone with Android operating system, is being sold only in US. But this is not true.
It is being sold now in different countries. Prices for the purchase with a contract are listed.

USA: $98 on Amazon
UK: Free from T-Mobile
Australia: Free from Optus
Singapore: $38 SGD, ~$24 USD from Singtel
Germany: 1€ from T-Mobile
Poland: 1 PLN from Era
Austria: 1€ from T-Mobile
Netherlands: Free from T-Mobile
Czech Republic: 1 CZK from T-Mobile

All those offers come with 2-year contracts which cost 40-60 USD monthly. Exceptions are Poland, where you can get 1 PLN price only with 3-year contract, and Czech Republic, where 1 CZK price is with ~$110/month contract.

On March 15 HTC Dream will be sold in France by Orange. No information about the price yet. Also in March it will be introduced in Spain by Telefonica.

So, 11 countries (9 - already, 2 - to launch in coming weeks). With localized experience, for sure. If you are interested anyhow in mobile Internet and improved user experience, and are in one of these countries - you are lucky. :)
