While we discuss whether to buy an iPhone 4S right now or wait for a totally re-designed iPhone 5 to launch sometime next year, an interesting comparison between iPhone 4S, iPhone 4 and Samsung Galaxy S II has been published by ThisIsMyNext. A chart lists all the features and specs for the three top notch smartphones available in the market. Even though there are two iOS devices against an android handset, the comparison mainly details the hardware “by the numbers” for the three handsets one by one.

About the iPhone 4S, the source says:

Clearly, it looks identical to last year’s model — but the iPhone 4S’ features and specs are all about details. On top of exclusive support for Apple’s new Siri “intelligent assistant” and dictation system, the 4S comes in a new 64GB flavor and ups the camera to include an 8-megapixel sensor with improved low-light performance and 1080p video capture. For CDMA users, the support for GSM global roaming should be a pretty big deal, too.

So, are you getting in line on October 14th at your local Apple store?
