Siri was originally a program in the AppStore which apple bought out in '08. They saw how cool it was.
Siri is really cut down. It can not open programs or anything. Just cool and simplistic. If it had more access to the system.. I hope the jailbreak could fix it, but I highly doubt it. All commands go back to apple servers then back. Bastards will block all cool commands...
Damn siri - No Sudo!
I tried!
Siri is awesome. I got the 4s (Galaxy2 was a POS. No build quality).
Siri is damn fun when you're bored!
Open the pod bay doors.
LOL, I've heard people with 4S bragging about Siri so many times, but they tend to stop using it after 2 minutes. I've also never seen them actually use it for something useful (apparently the traditional ways are faster)....but I've heard a lot of outcry for poor speech recognition and unsupported regions.
BTW the SGSII has a VERY HIGH build quality, what you are ashamed of is the build materials. There is a difference, learn it (eg HTC has good build material, poor build quality).
