It's so funny that people are upset over the announcement. The iPhone 4S IS an iPhone 5 - all the internals are new and everything has been updated and upgraded. The only thing that remains the same is its design... are people really getting hung up on it not having a new design? Seems silly to me.
Anyway, the 4S will make for a nice bump from my old 3GS. I won't consider an Android phone until Android handset makers have the balls to stand up to carriers and refuse to let them lock down the OS and preload the phones with tons of crap. Apple did it, so why can't Samsung, Sony, HTC, etc? I know I can root them but that shouldn't be necessary. Aside from that, I don't really like the designs of any of the current Android offerings and Android itself has a ways to go before it's fully matured.
