How about the most potentially fatal (literally) flaw: No handsfree operation. Google has it listed asn an "enhancement" with a medium priority. Dealbreaker for me. Like every phone I've had for seven years, you press the call button on your bluetooth headset (or your wired one), the phone says (through your earpiece), "say a command" and you tell it who to dial. Handsfree. Simple.
In this day and age, people are complaining about multitouch? PLEASE... how about making it a phone first, then go after Apple.
