Android G2 group buy
Androids have been compromised by being carrier and operating system locked. This means we can't travel with them and just swap the SIM card, and we can't remove unwanted Carrier software, access functions the carrier removed (like tethering via Wifi hotspot). Currently the Nexus One is the best solution for an "open source Android" — you have to void the warranty, but root and custom OS installation is just a click away without playing cat and mouse "jailbreaking" games. However, the Nexus One doesn't have a keyboard, a feature many professional and technical people need.
HTC's new G2/Z has a keyboard, and runs stock Android, so it's perhaps the best choice as an "open source Android." Perhaps Google will release it as the "Nexus Two," though a handset with slightly larger battery and numeric row on the keyboard would be nice. If not, the best best thing could be a group purchase of a particular handset from an unlocked provider.
