And lets be honest...who's going to need a 1GHz processor in a mobile phone? Maybe a few games will be able to use the power, but appart from that there is no reason to have the most powerful phone, with the most RAM and the fastes processor. It's not like you're going to start encoding movies in your pocket!
For me it's all about the UI...and the iPhone wins this no problem.
so why do you have a 3GS? why not get/keep the 3G?
this is like saying "i only do word processing so i don't really need a 2.5GHz Core 2 Duo". maybe not, but would you not like it if your computer booted up quickly and your word processing app launched in seconds rather than 10's of seconds? how about your browser? wouldn't you like that to open quick and render a webpage nice and fast? the browser is something that the 3GS does much quicker than the 3G. now apply that across the board. everyone has a thing about speed, so internal spec is important. if it wasn't we'd all still be running P3 and PowerPC processors in our PC's and Macs.
i don't really see how the UI wins "no problem" either. yeah, its nice and simple, but poor (understatement alert) notification system, no location awareness on key things like weather apps, toggles for features that drain power being hidden in subsections of settings... all things that apple needs to deal with just to catch up in my opinion.
like someone said a few pages back, apple have trapped themselves by not evolving the OS more than they have since its release, they either make a radical jump forward, or slip further behind the competition. with their set-in-stone yearly updates i'd be very worried if apple didn't make that leap this year...
