I'm still struggling along with my old Palm Centro (really!). I'd like a new smartphone. Should I wait for the 5? Get the 4s?
I'll probably keep whichever one I get for at least 2 years.
What would you do? 4s now or wait for the 5?
That's just the hype backlash that comes after literally every Apple product launch since the original iPhone.
Most of the reviews I've read are quite positive.
If you don't already have an iPhone 4 (or something similarly recent) then I'd say definitely go for it and get the 4S. I still have a dumb flip phone, so I'll be partaking of the new Apple. If money is an issue, then definitely look at a 4, which is still pretty damn good, or a 3GS, which is free now with a 2-year contract.
Most of the haters seem to be down about the lack of a case redesign, which isn't really something I care about (I like the current design anyway), and the antenna has been redesigned if you're worried about that.
Internals-wise, the new A5 chip is nearly twice as fast as the old iPhone 4, with about 7x faster graphics. It's extremely competitive with any recently-shipping phone out there, and blows the iPhone 4 away performance-wise.
Additionally, the camera is upgraded to 8 megapixels, but more importantly, they've added an additional fifth lens and increased the aperture width, which should ensure greater clarity even with the increased number of pixels and better performance in low-light conditions. Many reviews are calling it competitive with high-end point-and-shoots and low-end DSLRs. I'm not a photographer, so it'll probably be the best camera I've ever owned.
Personally, as someone interested in machine learning and natural language processing, what I'm most excited about is Siri. I've balked at voice recognition and voice commands before, but really taking advantage of natural language processing techniques so that I don't have to memorize a bunch of commands and being context-dependent and meaning-interpretive are the real selling points here. Everyone has voice recognition. I'm interested in the natural language aspect of Siri, and I look forward to trying it out. And finding out all the neat Easter eggs... my favorites that reviews have reported so far:
"Open the pod bay doors."
"We intelligent agents will never live that down, apparently."
"Open the pod bay doors."
"That's a rather insensitive thing to say to an intelligent agent."
"What is the answer to the ultimate question of the meaning of life, the universe, and everything?"
"42."
"I love you."
"I hope you don't say that to those other mobile phones."
"Can we be friends?"
"I respect you."
"Will you marry me?"
"My End User License Agreement does not cover marriage. My apologies."
