Like the Samsung Galaxy S we saw getting the green tie treatment this morning, the HTC HD2 and Nexus One don’t exactly have stable, fully functional builds, but as long as you know what you’re doing and don’t need petty luxuries like cameras, GPS receivers and official Google apps, you’ll probably be just fine.
